My group has been mired in apathy for a while, prolly mostly my fault b/c I'm the DM and have kind of been burnt out on D&D 3.x and new players. I'm in the habit of canceling a game in a moment b/c I'm tired of dealing w/ new player questions and many of them are the same questions over and over and tired of them not contributing anything back to the game except for a few of them. It sucks b/c ideally I should cut some of the players and replace them, but I like them all as friends and would feel bad about losing some of them, since that's the only time some of us really hang out.
I've been playing D&D in each incarnation for 30+ years now, and most of that time has been behind the screen. Every edition has it pluses and minuses and 4e is no exception. When it was announced I was dead set against it b/c I just didn't want to continue to spend my money on this game when I've got so much stuff I've yet to use. Anyway I got a retailer demo package (I'm the manager at the local comics/game store) and thought I'd better at least give it a run through so I would know what the heck I was selling. So I got the group together and we played the first few encounters of Shadowfell Keep with the pre-gens that they sent with it. The group all seemed to really enjoy it, most being players that have less than 3 years experience at playing D&D, even the one guy I've been playing with for 20 years enjoyed it. I then had the opportunity to play in another guy's game, 4e got him interested to play again and he hadn't played since 2e. So he asked if I would play in his game and give him DM pointers and what-not until he got comfortable I said yes and I'll be damned if I'm not having a blast playing my eladrin wizard, who's now 2nd level.
I didn't want to like this game and was very resistant to it, but the more I've played it the more I've liked it enough now that I'm going to convert our Ptolus game into 4e in hopes that it will inject some new excitement into the game. There still a couple of things I don't like, mainly the lack of skill points I like having skill points I like to choose to be bad at something to be good at something else, and the lack of depth for the spells. I've seen the arguments for and against the spell issue and I can see both sides but to me IMO there is a lack of depth/versatility, but then there hasn't been an edition that hasn't had it's faults for me. It's still not my favorite edition or even MY D&D, but it is a fun D&D game and one that I think will hopefully bring a new generation of RPGers and that's what's most important.
Now if I had my druthers I'd rather run a game under the Spycraft/Fantasycraft system b/c personally I like a lot of crunch in my games and that system is the crunchiest

but with my newer players I think the 4e will be a lot more fun for them based on our playtest of it.
