Visuals: it has to look nice, clean, crisp and it must have some style. If I can't tell what is what, I'm not wasting my time.
Agreed. Not the same as graphics. Kane and Lynch may look beautiful, but it still manages to look like crap in the end. Games like Kirby's Epic Yarn have the Wii's graphical limitations and can still look great by using a creative art style.
OT: After gameplay, that would be:
1. Story- Can't be an emotional game without an engaging story. Games like Borderlands and Team Fortress 2 bypass this with superb gameplay.
2. Visuals- Just like Sean Devlin says in the quote above, a game needs to let you know what things are and reduce eye strain. I will pass on a game that hurts my eyes to play. Also, I don't want everything to be colored like the "Next-Gen" SFX in Halo: Reach's forge mode.
3. Replayability- If I can't see myself toiling hours upon hours of time into a game, I'd rather rent it. Applies to both multiplayer and singleplayer games. A game should make you want to play it again and again even after the novelty wears off.
The following are in no particular order:
4. Immersiveness- Just like replayability, a great game shouldn't even let you know you're in the game. You're fully immersed in the game, and you don't want to leave the world the developers lovingly crafted.
5. Choices/Freedom- It's probably just personal preference, but I want multiple ways to approach a problem. Let's say a guy's running up to you in Reach's multiplayer and lets loose a few rounds of Assault Rifle and you have the same weapon. Back in the "old days" when you didn't have the choices Reach gives you now, you would have to:
a. Run towards, him, return fire, and punch at just the right moment
b. Run away
c. Toss grenade
d. Die
Assuming you don't want choice d., you were very limited to what you could do. Now, you can sprint away faster than he can chase after you at normal speed, roll to avoid getting shot, armor lock and wait for reinforcements, drop shield and give yourself a breather, active camo when you turn the corner, or jetpack into the sky and rain some hell. In addition to the original 4 choices, you're much more free to engage him the way you want to. You could also have avoided the situation entirely by using Active Camouflage to sneak around him.
On the singleplayer front, Operation: Flashpoint drops you off kilometers from your destination, and you have to pick your path through the area. In other game genres like RPGs, you're given moral choices and multiple ways to find a solution to the problem at hand. Oh no! The local gang has appeared! Local gang uses: intimidate! It's not very effective. Hero uses: persuasion/attack/run away. Local gang is called off/Local gang has fainted/Local gang is tired, and doesn't feel like chasing you. Conflict resolved.
6. Community- I've given up on the recent Call of Duty games for this very reason. The gameplay works, the multiplayer was functional and very satisfying, but the gaming community around the recent Black Ops and Modern Warfares drove me away. I can't put up with 13 year olds who just sit around during the lunch break and only talk about their latest kill in BO/MW2. The first thing I hear when someone even mentions the words "black" and "ops" in the same sentence is: "Did you buy Black Ops yet? Dude, I just got this awesome kill when I..." Because of you, no, I am not buying Call of Duty: Black Ops.
7. Humor-You can't be all dark and gloomy. Try to brighten the days of the people playing the game. They're here mostly to have fun, so give 'em what they want. A couple creative achievement/trophy names couldn't hurt.
Edit: Crap, forgot "Soundtrack." Oh well, I'm tired.
