World at War (turn based GRTS).
Got BF3 legally for free, disliked it very much.
World of WarPlanes, that was seriously bad and I joined the Beta for freebies. Still online and active and getting better. Fly-games aren't my thing, never got hooked.
Its mildly fun until you realize its basically a p2w grindfest with a toxic community and one of the WORST botting infestations I've ever seen. What you see in the above videos isn't just one isolated area of botting, its like that for endless (ingame) MILES. I positive there's more bots playing than actual humans. 'Don't play korean MMORPG's' is the moral of the story.
Saints Row 3 wasn't bad, but it was just disappointing compared to Saints Row 2. Rage was also a bit disappointing, and the combat wasn't my taste since it took forever to kill someone in that game.
I can't really say what's one of the "worst" games I've played. Battlefield 3 has good gameplay but a scummy business model where expansion packs are quite necessary to make the game more fun. The Sims games, which also use expansion packs, are somewhat less of a big deal as the player is only bound by their imagination, by mods and by the extent to which the game is supported by EA.
Now I would say Dragon ball Taiketsu for the gameboy advance but that's just too easy since it was an anime game on the gameboy advance. So instead here's my pick from the PS2 era...Bad Boys: Miami Takedown. Didn't know the Bad Boys movie franchise had a video game? Neither did I until I randomly got it for Christmas and played it for a bit...
