I've played D&D on and off since I was at school. A bit of a 2nd ed veteran, I skipped 3rd and 3.5 and I've just started back with 4th in the same group that I used to game with.
The core rulebooks in this set are of a high production quality, the rules are clear and well thought out. We played our first game last weekend and everyone loved it. Despite living in completly different parts of the country these days, may group can't wait to get back together for our second adventure.
Do the rules seem more like a video game? Yes, they do. Does this allow for a better combat gaming experience? In my opinion, yes. You don't even need to use all the expensive miniatures and tiles, a grid and some tiddlywinks will work just fine.
Some have complained that it's dumbed down and that there's no roleplaying, but I say that's daft - you don't need rules to roleplay, you can add that in yourself, there's no extra charge. I firmly believe that D&D has to evolve over time to entice new players, excite old players and to avoid stagnating.
So, for new players: If you like fantasy and games, this is a new incarnation of the grandaddy of all rpg, buy these books or try out the £10 starter set (also available from amazon). If you're an old player: Don't listen to internet whinging, give it a shot and make your mind up for yourself!
