Obliv *SMACK* okay, okay. Something else then...
Mass Effect - I heard so many good things about it, and I have no doubt the story is good. But the combat system was just a mess. It was not challenging, it was just frustrating. I quit the game because of that,
turn up any games difficulty enough and it becomes like that. I enjoyed combat on Mass Effect 1 on.. Can't remember the name, but it's the hardest you can go in your first playthrough. The real killer for the ME series is the fact I can only play it once or twice, then get bored. But it's like that for all games with me (campaign's anyways). I also hated in ME1 how you couldn't separate your squad, meaning, one person move left, the other move to the right. So most of the time, I would have them both sit in one place, run up to the enemy, shoot them a little, any Krogans would follow me, and fall straight into my Squad's trap
Oh, and Halo 3:ODST was a let down. It should have been an expansion.
Gears Of War 2's multiplayer. The campaign was good, Horde mode was ok, but overall, the multiplayer was generally "Luck" based, and has now become (thanks to the updates), nearly impossible for Gears 1 veterans. Heh, even though I'm not a Gears 1 vet, I'm a Gears 2 before the updates veteran! meaning I <3 to lead my shots through lag.
