Well, here are my games:

As for GTA4, well, for starters the controls are wonky and often unpredictable, and it's like they do as much as they can to inconvenience you at every step -- you have to mash a button to run, so you can't look anywhere but straight; cars control terribly, and the vehicle management system runs into the annoying dilemma that it's only close to being fun (or tolerable) to drive the best ones, yet they're so rare that it'll take a while to find one usable for that high-speed chase you're currently trying out; shooting from a vehicle seems to do
all, but it skews the camera angle so you can't see where you're going; obnoxious lack of checkpoints; and any and all work that you put toward building an inventory of weapons is undone instantly if you get arrested or killed.
Even worse, if you die during a mission, you'll respawn at the beginning of the mission,
minus any ammo you spent during the last time you tried the mission. So you're expected to do the same thing, but with less than you had before. Then less again. And again. And it takes forever to do anything in this game, so it's quicker to just reload every time you fail than it would be to find an ammo shop and buy it again. Not that that's even remotely quick, since you load at your safehouse, which is never anywhere near the objective you're trying. And either way you still have to find that elusive playable car to even stand a chance.
It's just so muddled with boringness and inconvenience that really the only plausible way of playing this game is not as a single-player experience to go through, like a normal video game, but to do what any sane person does in all GTAs -- spawn tanks with cheat codes and blow the world to bits. I'm pretty sure the only reason this game was received so well is that now you can do that in multiplayer online (and the free play mode with friends is the only online mode worth trying, the auto-aim makes all the other modes incredibly stupid).
Save your money.
