I skimmed the basic rules, and like what I see overall. Been playing since '84.
Sure, there's stuff I'd change if DMing it. But what struck me about 5e is its compatibility. I see no problem in using a 1e or 2e surprise/initiative, or even changing it based on circumstance - size of battle and sofoth - I can throw in my simplified weapon vs. AC, and tone down the frequency of advantage mechanics with previous editions, or on the fly rulings. I already use free cantrips and open multiclassing.
I disagree with the notion of "if you're going to houserule it, why bother", at least personally. I remakn interested because I have never played any D&D btb. The very notion of that seems alien to me. But 5e looks like a strong, versatile base from which to play this game I love, informed and enhanced by the richness that has come before.
I'm also interested in 5e because some younger gamers are. It's ok with me if some think 1e is hokey or too much like jazz. I want to see the hobby survive and flourish, and not fall into generational cliques.
