I put some more time into the game today, and it's pretty impressive. There seems to be a ton of content and the game is pretty damn funny. Killing people is so much fun in this game. The fact that they are little 8-bit people actually makes it easier. I would sometimes have pangs of conscience killing people in the GTA games because you're hurting real looking, real sounding people. The cartoony look of Retro City Rampage lends itself better to the kind of rampant violence GTA games became known for. It's less disturbing, and thus, more fun.
Plus, there's some funny jokes as the expense of the poor civilians you'll be murdering throughout the game. You can hit someone and send them flying into other people in a straight line and get a "strike!" bonus, like a bowling game. You can also stomp on people Mario style, or pick them up over your head and throw them into the water. I especially love when you're on fire and you have to run around setting other people on fire. Killing people is actually like a sort of mini-game. You kill people in quick succession and get multipliers and chain bonuses to build up your score
I'm amazed at all the GTA III staples in the game. Pay and sprays, police awareness levels, lots of weapons, various side missions, it's all here. Story missions have checkpoints too. Awesome! You can even leave a mission and come back to it and your checkpoint will still be active. You can replay missions too. The references are awesome. I don't mind this type of humor. You'll see lots of funny cameos(although the game is careful not to make any of them too accurate so as not to infringe upon copyrights). I actually hijacked a green van from a ninja turtle and stole a talking car from a certain Baywatch star LOL
I also had to power up a recognizable time travelling car to jump through time, and had to build up power in the only way that made sense - running over ever civilian in sight!
Here's one of the first reviews of the game. I don't much disagree with it.
