As someone who has never played 1.f9, why (except pouncesins) do people prefer 1.f9 so much to later cmxl versions?
As for favorite version, I made my own actually, based on 2012. I reverted pretty much all of the changes to items and a couple changes to skill to how they were in omega003 (there were too many nerfs in 2012 and I feel like they were done without a good enough reason), removed lantern anchors, porkchops, added a lot of QOL changes like bigger inventory, mass sig/DE, mercs can equip all items, "flask of renewal" (oil of renewal which is 50 times more expensive but has 50 charges), moon cookies & goodberries at vendor etc. Also playing with BaseMod which means I've got neat things like Nihlathak portal fix and ctrl click to inventory/cube/stash. Plus some other small changes like renaming items with retarded names ("tldr", "QQ", "Noob Loop"
) and changing the stats of a couple of uniques to make them at least somewhat useful..
