Kind of hard to agree on what a "terrible game" is, did it have to be a glitchy and broken game that crashes or just an offensive pile of racist garbage? Since I mostly stop playing games that are broken that leaves games that I hate (that is made me regret spending the time with them and wanting to throw stuff at the developers), which quite often are games that are functional and bug free and even sometimes AAA titles.
Quite a lot of the terrible games I've played I stoped before the end so this is just the other ones, those that I have finished.
Going through my list the following jump out.
An old RTS that really made me furious, it was a combination of RTS and CCG. You build a rather good force to attack the enemy base but it turns out they have the "Destroy All Your Forces" card and blows them up ... and 5 minutes later you have built a new force and they play the same card again since you draw new ones all the time.
Ah, yes. The plague has struck ... no, not the zombie plague, the skin disease that everyone on the island is suffering from. Total crap annoying game, I want my time back! At least you can skip all the cut-scenes so the suffering was somewhat lessened.
Old RPG game where the story really is not associated to the game. You can talk to a totally new character and she in her thoughts admit that she wants to prove herself to you cause she loves you ... yeah. Crap final battle, turns out that all the items you have collected doesn't matter since you get all the best gear in a chest just outside and there is only one way to win the final battle ... heal the NPC that kills the boss for you.
Assassin's Creed 3
Yeah, this is a well made game with good graphics and zero crashes for me but I still hate it. I loved the sea battles and the combat felt fun at time. Starts of with some of the worst Badass Paradoxes I've seen.
Mr "I jump and kill people from above" Connor enters a church and gets ambushed by his father from above ... yeah, thanks game. Since you want me to associate with Connor, and you say that Connor is an idiot, you are calling me an idiot ...
Oh, lets see. Here is the final boss in the middle of a circle of soldiers, I'll use my assassins to open up a hole here with the Sniper and Ambush specialist and when he runs off towards this side I'll ambush him under that tree ... no? No, apparently I walk into the group of soldiers and get captured ... thanks for calling me an idiot again game.
Aha! Finally the boss again, now I get to chase him down! Oh, this is going well, I'm almost up close enough to tackle him. Why doesn't the "pull and shoot gun"-button work? It has worked before during chases? Oh, so instead he runs into a ship and I follow and gets disabled and he gets away ... yeah, frakk you too game for calling me an idiot again.
And then the whole helping assassins are never used except during their own missions, the use of them for missions on the east coast seems totally useless and the trading/crafting doesn't matter either. The whole finding stuff seemed to easy since you see it on your map, the only thing to do was to walk up and get the stuff. And half the cut-scenes you can skip but not all of them.
