Another newbie posting, so beware, seriously misguided and heavily opinionated comments might follow!
I loved RC D&D. I loved AD&D 1e. I liked AD&D 2e. I enjoyed D&D 3.0 and was a little perturbed at D&D 3.5. I was downright flabbergasted at the announcement of the release of 4e.
Now, I'm NOT saying I won't like 4e. How could I possibly know that? I'm not a beta tester. I have no earthly clue. If the difference is as great between 4e and 3.5 as it was between 2e and 3.0 then I can't even begin to guess what it's going to play like.
I lost sight of how the game was "supposed" to feel somewhere along the line and it took the 4e announcement for me to really sit down and take a close look at "why" I became a little lost. That's a whole different story though...
Bottom line, I found Castles and Crusades to my liking. I've read a few DCC modules and I find they're to my liking as well. They remind me of the sheer "coolness" factor while playing as a young man.
Will I buy 4e? Certainly not to run, but to play a game in? Maybe. Will I continue to purchase DCC modules, whether 3.X, C&C, AD&D 1e or 4e? Quite likely.
