By now I'm probably nearing a thousand hours of Pokemon games over the years, with Ruby around the 3-400 hour mark. Diablo II and its expansion sucked up the next largest amount of time followed by Gran Tursimo 2 or 3.

On PS3, I've spent around 150 hours on CoD4, and easily 100 hours playing Burnout Paradise. I fully expect to shatter those records when Gran Turismo 5 comes out in 2015. *sigh*

I had the same problem when I beat the game on Hard. Unbeknownst to me, the game gives experience when the difficulty is set to Hard. Put the game on Easy for a while and just ride the tracks around the city fighting any enemies you come across.

Half Life 2

Halo: Combat Evolved

Counter-Strike

This is one of my biggest gripes with most new games. Tough achievements (like ME2 on Insanity or 100% in MW2 Spec Ops) should have avatar awards so that you can show off your favorite achievements to your friends.

PS3 is MUCH more reliable than the 360, but that's not to say they're not bulletproof. I've had no problems with my launch 60GB system, so take that as you will.

If you have it reserved, 100%. If not, ~ 99%.

MGS4 LE. That was only because I'm a huge fan of the franchise.

Otherwise, I don't bother...

Same here, I was a HUGE fan of MGS, so the extra price was almost an afterthought. Overall, the Halo 3 Legendary Edition (with cat-helmet) was the most I've ever spent on a game at $130.

EDIT: Brain fart. Rock Band was around $170. Good thing my friends and I have gotten our money's worth out of all of these expensive games.

Valkyria Chronicles, Disgaea 3, Command & Conquer are all good strategy games for the PS3. I think RUSE is coming out soon, too.

I own every game except for the first, and I'd get it without hesitation. Getting Trophies is a good excuse to replay one of my favorite series of games.
