That first one is interesting. Care to explain more as to why you hate them? Don't know if it's controversial or not, but I'd take a PSN/iOS game over a retail game any day of the week.
To be fair, there are a lot I haven't tried. They simply don't interest me and a lot of them usually don't have demos available. My second point has a lot to do with this as well, as these particular games usually have no story or a story that is only really there to get the player from point A to point B.
The ones I have tried are those that I get for free from Playstation Plus or the Welcome Back thing.
This includes:
Comet Crash - decent game... not much else to say, one of the few I bothered to play to completion, but I must have been pretty bored to do that.
Red Faction: Battlegrounds - An utterly terrible and shitty top down multiplayer vehicle combat game. Nothing good about it at ALL.
WipEout HD (does this game even count? I'll put it here anyway.) - don't get the hype with this game. Played it for a bit, tried to like it, but just wasn't having fun.
Super Stardust HD - Hey, I actually liked this game! It was fun!
Dead Nation - Played local co-op for a bit with a friend when I got it. Didn't have fun with it.
Bomberman ULTRA - I used to like Bomberman... didn't really play this one. Not sure what to say here
Echochrome - This game was neat. I actually played it for a bit (like a few hour sessions for a couple days) but I got bored quick.
Crash Commando - I loaded this game up once and played it for abour 15 minutes. Game wasn't for me.
Costume Quest - This game was decent, but then I encountered a game-breaking bug and I will not be playing it ever again. Fuck. That. Shit.
Hydrophobia: Prophecy - I played this game for about an hour and could not believe how bad this game was. The voice acting was absolutely terrible and there was nothing interesting about the gameplay.
Back to the Future: The Game - This game isn't too bad, it's keeping me entertained right now while I have no other games to play.
Looking back on that list, maybe I shouldn't renew my Playstation Plus subscription... There were a couple that I "liked" there, but I would much rather be playing a AAA retail game, and I never would have spent money on ANY of these games ever.
Are there better PSN games out there? Well, probably, yeah, but I'm pretty sure I would rather spend my money on a retail game.
Usually these PSN games just don't grab me. I find their character design boring, their soundtracks unmemorable, their stories uninteresting or boring, and they don't even make up for it in gameplay I find.
Hope that was a thorough enough explanation for you =P
