I think it's a great idea. Cutting the fat from the already multiplayer focused modern fps. I hope they take the full price tag into account into the games life cycle. Possibly free DLC. I certainly hope it's more wallet-friendly than most of the other micro-transaction laden garbage that comes out.
Seeing that it's still full price I instinctively feel that there should be more maps or an extremely lenient DLC plan.
That being said, this game would have been undeniable if it were $40.
For amount of content looking at what I consider value if they have I'll say 25+ maps at launch I could be cajoled into saying that's not a bad value anything under 20 is a damn rip off for the price.
That and if it was $40 I wouldn't even blink at the value proposition.
