Fictionvision: I'm going way back with my picks.
Zelda 2 and Mario 2. Both games were OK, but not as good as their sequels. Zelda 2 especially disappointed me as a kid. In the end though after playing both I went looking for something else and discovered Mega Man 2, which I loved.
mondo84: It's funny, I rather like both Zelda 2 and Mario 2. Well, Zelda 2 was really tough and frustrating at times, but I liked how they did something different. And Mario 2 was just kind of weird, but still familiar enough
The main problem with SMB2 was that it deviated from the original in significant ways, but didn't really add anything compelling to make it worth it. The Lost levels at least were more in keeping with the original SMB.
Zelda 2, was a product of the time. I think if they were doing the same game today, they wouldn't have needed to throw in all that find secret spot X that we won't hint you need to find stuff. Other than that, it wasn't too bad. Although, I don't think I ever managed to quite beat it.
I did not like Quake 3 or any of those other games where the developers decided that they could just substitute multiplayer for a competent SP AI and a good campaign. Also, I disliked that Return to Castle Wolfenstein stealth BS and Doom3 in general.
They don't make me hate the original games, but I think they should have gone back to the drawing board on those.
Starcraft 2 did however make me hate the original game. I think what happened there is that it revealed just how much the original was lacking and how badly it's aged.
