Assuming the gameplay is good, I tend to look at a dollars per hour ratio. I'd consider 5 hours of game for $10 to be a good deal. Go lower and I might start looking at disc-based games, instead.
Edit: And a similar ratio for new DLC. $5 for 2 hours of levels or so.
Edit edit: Hold on, you said 'match types.' So this is a multiplayer FPS? If you can make some seriously fun gameplay and well-designed multiplayer maps I'd be all over this game like stink on a monkey!
