Inspired my the "fritz and shrub" thread, I messed around with mods, because the worst is, I blow ET. oh well. so far, I've done a few graphical ones (and TONS of skins. a new one each week) and I've only run into problems with W:TF and fritz. I'm gonna mess around, and with anyluck, be playing it in no time. all it appears to be is a conflict in skins. I can correct that.
Skin/sound/models/etc mods are no issue - ET and Fritz don't care what your using. When you try to use diff weapons tho - understand that it may not work, unless the weapon is EXACTLY like the ET weap it replaces (ex: say a gun works EXACTLY like the MP40, its just a diff model - that would be alright).
The code that controls how weapons behave is in the same file the bot is in, and isn't possible to change/access without me doing so, so any weap you replace will have to be a 1 to 1 replacement.
And I've already stated that I won't be adding/changing anything that would break cross platform compatibility, so that ppl who run windoze servers can have mac/linux clients connect, so new weapons is not possible.
