Hitman Blood Money is pretty good. It's not a perfect game, but it's one where the FUN FACTOR is pretty much as high as it can be, one of those games where you're easily able to look past its shortcomings.
Most of the shortcomings are around the AI behavior once you turn it into a RUN AND GUN FPS, AI behavior of crowds, various bugs (sound fucks up sometimes, some people get invincible by being stuck in a death animation (this is rare and has happened like 3 times ever to me)) and generally not enough fun levels

the fun levels are brilliant though. especially the casino.
also DEAD RISING is a pretty acquired taste imo. i thought killing zombies was really, really fun, but once you get a couple of days into it (in game time) there's just a ridiculous amount of zombies which makes it really hard and frustrating to do shit like grab a gun from the gun shop. and some (most) of the bosses are ridiculously hard.
the zombie killing part is really really fun and inventive though and kind of sandboxy, in the way that you'll make up cool scenarios for yourself and ways to kill them off. it's only too bad it gets way too crowded every once in a while and it's too bad those bosses sometimes pop up

for some reason it reminds me of state of emergency.
