We're an older group of player who love their 2nd edition, but the D&Dn is really going to change things. We had a really hard time getting anyone to switch to the 4th ed. All the skill and complex BS just made the game no fun, and rather than ignoring so many rule we just dumped it and went back to 2nd. The playtest we're running right now is going amazing! The players are having tons of fun and the simplified check system is mixing it up. I'll keep updated as we progress further.
