For games that released in 2008:
1. Resistance 2
2. Metal Gear Solid 4: Guns of the Patriots
3. LittleBigPlanet
Gears 2 would be on the list but on average it usually takes me anywhere from 5 up to 15 minute to find a match online. Thats is unacceptable. Until the speed up the matchmaking it remains off my top 3
