My hope is that a renewed interest in 3.5 overall may result in a renewed interest in LW to get the d20 files into order.
3.5 was my last and final stop in D&D, I still run it today, modified of course. There are still too many things I find problematic in 3.5, and I've done my very best to correct them.
As for 4E, I tried that out, and I understand the modular aspect makes it a much more flexible system, but also lends itself to, as a previous poster put it, common builds because there isn't enough balance in the system. There wasn't in 3.5 either, but it was manageable, I digress though. The main problem I had with 4E is it was really created to appeal to console game players. Nothing reminds me more of it, many of the powers are like clicking and icon and waiting for it to come up again after cooldown. Frankly, why would you do that in P&P when many console games do it better. And the fact that roleplaying has been completely disregarded for feats, powers, equipment, and a purely combat oriented approach. Gaming has progressed to fighting for experience, and anything else you could do to further a character in experience is completely missing from the rulesets.
My 2 experience worth.
