Well l2-scripts are in my opinion kind of pricy and i would definetly think about all the alternatives before throwing my money on the russian files(~400 eu) which in my opinion aren't much greater either, so i don't really think they're worth so much.
The problem is the lack of features that l2jbasic has, as i don't have time at this point to develop the whole community board for buffing/shop/etc. , aswell as most of the other features that are already implemented in fandc or PS. EoA is running on PS and it had quite many players, i persoanlly played there and can't say the game quality was totally shit, it was decent. With proper developement it can get to good, but that's just my opinion.
