I like the rules so far, lou. Especially the idea about "non-scheduled matches" being like house shows and only really counting for half a point (I'd stick with half, btw, but limit it to a max amount of points you can gain in these types of matches per week, month, whichever). Ie: wrestle non-scheduled matches all you want, but after a certain point you'll stop gaining half-points for it.
With something like this, I 100% agree with the CAW-only rule. Normal efeds, where advancement is based off of promos, it doesn't really matter if you use a real wrestler. However, if in this game the pre-set WWE wrestlers are miles ahead of the CAWs (you only get a set # of stats to play with) then you're already at a huge advantage.
