1. No auto-aim...? YEAH!!! A bit more towards skill, it is.
2. People have different tastes. I, for one, don't mind more realistic gameplay.
3. What did you expect? At least I didn't expect a proper sandbox game, I expected a somewhat linear game with an open world.
4. Too bad... Well, unless you're just stupid and missed something obvious, the game really is buggy. I suspect the latter.
5. Can't say much about this, I've only tried Godfather 2 and haven't even tried Mafia II.
6. There are funny games, there are serious games, but both can be fun to play in their own way. Here, GTA IV is the funny game and Mafia II is the serious game.
Despite not having played Mafia II, I had to share my own view on the issue. All in all: you were expecting a different type of a game than you should have. The game probably is good but it's not a game for you. You like different games. Apples and oranges, you know.
