I call it "enhanced core"; I change all kinds of stuff but it should still feel like you're playing core 3.5. Originally I wanted the game to go to about 10th level (at half speed) because as we all know, high level D&D falls apart. Then I started to think about all the monsters up to about CR 13 that I really like, and all the 6th level spells I'd like to include, so I said fuck it, we'll go a bit higher, but at an even slower pace. Now I know, you can throw CR 13 monsters at a level 10 party no problem, but still, lvl 12 feels optimal to me.

It isn't really "E"12 like E6 where you play at 6th level and continue to progress via feats.
