Normal
I always felt it was weird that they consider a "season" to be 10 months. I think they said they would like to do it for 3-4 years which would make for 4-5 seasons. I think that would be a great run. I imagine that the principal of diminishing returns will happen unless they have a fanbase that supports every last release so while I think there are enough great or at least enjoyable games to fill about 10-12 seasons, that anything past a fifth "season" will be a pleasant surprise.
