Mods, okay, you had fun changing the fonts, please change it back, it's getting painful to read stuff
I haven't played any games I've considered TERRIBLE, or the worst. But I'll just mention a few I particularly didn't like:
Burning Rangers, Sega Saturn: I never quite understood how to play this game, it looked like absolute garbage even for a Sega Saturn game, and thanks to me not understanding it, I never had fun playing it.
Call of Duty: Ghosts, platform doesn't matter: ...That game... exists. I actually have far more to talk about with this game than any of the others I'll be talking about here.
If you're a fan of CoD, you more than likely hate this game, too. You'll have a hard time finding someone that actually likes this game, actually. Next to no CoD fans even bother defending it. Ghosts effectlively shat on everything that made the previous games good. I won't bother going on detail about just WHY this game came to be the trainwreck it was, it's a long story that started way back in the MW2 days, but I'll explain how the game itself we got is.
First of, the graphics. If you played MW3, you know that Infinity Ward (or what was left of it) really must've suddenly got a thing for the colour grey, since MW3 was pretty greyed out. Still, it wasn't that bad. The game looked a bit ugly and somewhat depressing, but it worked. But they went *waaaaaaaaaaaaaay* overboard with it in Ghosts. The entire game is pretty much in greyscale. In fact, in that ridiculous and infamous space level, if you actually look at the Earth itself, you'll see even that didn't escape this decision, since it is also somewhat greyed out. This made Ghosts a *very* ugly game to look at. Also, in Multiplayer, enemy players blend in *very* well in the background, but I'll talk about the Multiplayer in itself more in a bit. Ghosts is also pretty much unplayable on a CRT TV. An entire 1/10 of the game is off screen on both sides of your television, the game gets a bit blurry and smaller text is borderline unreadable.
The Campaign... is terrible. More specifically, the story. You might be thinking "Oh, but the story in previous COD games was never something to brag about", but atleast they weren't this bad. It's very awkwardly paced, the missions aren't that fun to play, and dat ending. Apparently, getting shot in the chest by a .44 Magnum round, then getting blown up, then getting stuck inside a flooding container just isn't enough to kill the main villain.
And now, the Multiplayer. Easily the worst MP experience I've ever had. The gun balance, while better than, say, Black Ops 1 or MW3, still frankly stinks. The MTAR (which for fuck's sake, Ghosts, is NOT a Submachinegun!) reigned king over all weapons in the game for a long time. There were way too many perks, and they were all just perks from earlier games except stripped down into many parts. Deadeye is literally just Stopping Power that works randomly. Now, brief history class:
Deadeye increases your current bullet damage by 40% much like Stopping power did, but while that doesn't sound bad, you must remember that the three CoDs that HAD SP, CoD4. WAW and MW2, had every gun in the game somewhat weak to justify its usage. The average amount of bullets to kill in those three games without Stopping Power was 4 for automatic weapons and 3 for Semi Automatic weapons, and using the perk would effectively make you need one less bullet to kill. In Black Ops 1 onwards. Stopping Power was removed, and most weapons were given the effects of said perk by default, so now Automatics killed in 3 shots and Semi Automatics in 2. Even though Infinity Ward effectly brought that ability back for Ghosts, they still kept the default bullet power of the games where this ability was not present, so if you do use Deadeye, it's like you're stacking TWO Stopping Power perks in your gun, so now you have 900RPM Automatics killing in 2 shots, and Semi Automatics killing in... 2 still! The 40% buff still wouldn't give you enough power to kill someone in one shot to the body. The only thing that makes Deadeye different from Stopping Power is that it only works once every 4 shots (once every 3 shots if you kill 2 people and every other shot if you kill 5 people) which disencourages its usage in slower firing or Semi Automatic weapons.
So thanks to this decision, Semi Automatic weapons became useless and Automatic Fast Firing weapons became too powerful, and thanks to the lag (something this game definitely doesn't lack), most of the time you can literally get killed in less than 10 frames depending on your connection. Now, the maps. CoD was always about small maps and fast paced arcade action. Black Ops 2 took this too far and made every single map in the game claustrophobically small, so people complained. Infinity Ward saw this during the development of their upcoming game (which was Ghosts) and decided to change the formula of the maps. So, when we got Ghosts, suddenly it was the complete opposite of BO2: The maps were way too big!
The maps were too big, too open and barren. If even in small maps it was sometimes possible for you to run around everywhere and not find a single enemy for a minute or two, in the big maps, it happens all the time, basically! The maps were so big and so slow paced, most matches would actually time out rather than finish through score. it also slowed the pace of the game down to a crawl and made the Shotguns useless.
Overall... Ghosts was just sad. Advanced Warfare was a bit better. A tiny bit better. Slightly better.
Touhou Project Wars: I'm putting this since it has been previously mentioned here in this thread. Sure it's a fangame, so I should give it a break... but I won't. The game is very boring and repetitive. You need to keep getting money to buy new Gasha dolls and train them, so this means plenty of grinding to get money, and then even more grinding on top of that to get them leveled up. Boss Fights are a cruel joke. I've never had one that lasted less than 280 turns. The RNG keeps healing them everytime they're about to go down, then it keeps healing me when I'm about to go down. The story is on par with Ghosts in terms of quality, and that fucking SI protagonist is so damn annoying!. The cutscenes sometimes allow you to choose what you're going to do or say next, but, atleast to me, it doesn't seem to make that big of a difference. It's not the worst thing ever, you can definitely have some fun with it, but ever since I've stopped playing it two years ago I've never felt the urge to come back to it even once.
