This release got me back into aoe2 but I got to rank global rank 50 and then realised I wasn't actually pro, I was still a noob but all the good players play on voobly.
voobly is actually a much better service once you get it set up, less likely to lag etc. graphics are identicle, only thing HD has is better water textures. also has much more players than steam overall.
voobly is where entire the competitive scene is, just had a 50 thousand dollar tournement, not bad for such an old game. voobly isn't perfect I don't work for them honestly, its just that its free and WAY better than HD which was a complete rip off in hindsight.
