4+ player couch games - looking for suggestions

Hey,

I invited some (7) friends for the weekend and I'm looking forward to you suggestions for some good games. The games must have local coop and they must be playable with controllers. Preferably games in my Steam library or ROMs (console games). Thanks for you help!

Edit: We'll be more than 4 players so we'll likely be switching controllers, so RPGs and games that take great effort to learn probably won't work well.

Edit2: So far I got these games on my list:

Ps3

• CoD MW3 Survival
• CoD BO2 Zombies

ePSXe

• Crash Bash

Dolphin

• Bomberman Generations
• James Bond 007 - Nightfire
• Mario Kart Double Dash
• Mario Party 5
• Super Smash Bros. Melee

Steam

• Awesomenauts (3 players)
• Castle Crashers
• Monaco
• Really Big Sky
• Shadowgrounds
• Super Hexagon (hot seat)
• Trackmania 2 Canyon & Stadium
• Trials Evolution Gold (if uplay will send me my password resetting link)
• Trine (3 players)
• Trine 2 (3 players)
• Worms World Party (hot seat)

Edit3: Thanks for all you responses, we had a great weekend! ps: Castle Crashers is awesome!
