Any game that i can run around killing zombies with chainsaws and molotovs with my girlfriend, im happy with. Since the first L4D came out, i was in love. No one can get tired of killing endless zombies. Yea, ill admit, i have gotten tired of playing both L4D and L4D2. But come back a week later and it feels like a brand new game. That is one of the best things about this game that rarely any next-gen games have, re playability. Add a variety or weapons and brand new melee weapons and you will be happy. The campaigns are fun, not too long, not too short. With many level difficulties for anyone to have fun playing. Yes, i do play L4D and L4D2 with my girlfriend, and of course shes not the greatest. Ill put it on normal, and she will have fun playing, not too hard for her. While i play on advanced/expert but i still have a blast playing. Its a fun game to play serious with a bunch of friends too. Expert is pretty ridiculous and i don't know many people who can beat it, so there is always a challenge left while playing. Overall, i think Left 4 Dead 2 is one of the top games of all time with great replay and just fun overall.
