-snip-
I'm actually going to step in and defend 5e here, as someone who has DMd both 3.5e and 5e (and read 4e, quickly deciding I didn't like it.) Sure, the base rules aren't as nuanced as 3.5e. This is very much not an issue - it isn't difficult in the slightest to add in new skills etc..., and the extra streamlining is far more beneficial IMO - in my 5e game the only people who had any difficulty making characters were the two who had played before in 3.5e and so had missed off backgrounds (another nice touch, I feel, especially given how easily new ones can be made) and the first time player who hadn't done known spells as a wizard - so 3 minor things in a group of 6. In comparison, I spent my entire first session of 3.5e with my previous group fixing characters.
The flatter progression also looks brilliant, as it should make orc hordes a valid threat at any level - I haven't had a chance to test this though.
I do agree that 3.5e offered slightly more options (interesting play-wise) straight from the rulebooks, but I found in 3.5e my players mostly didn't use there options as there were just too many of them to choose from. In 5e, the players are far more creative, as opposed to just looking through their skill list for one that looks like it might be helpful.
Anyway, my 2c as a DM.
