User blog comment:Krufix/LoL and HoN, The truth./@comment-24.209.97.122-20120510015655

Personally, I think that the 3 major MOBAs (Not counting the original DOTA) going around now a different interpretation of that famous Warcraft 3 map. Although never playing it, it seems to me that HoN took ideas (Stats, A dark faction and a light one, courier, ability to eat trees) and heroes (Sand Wraith is Spectre, Devourer is Pudge, Chronos is faceless void, Slither is Venomancer, and so forth) from DOTA. However, the game also seems to be growing and becoming more original.

LoL, however seems to be its own game vaguely based off of DOTA. While HoN may copy entire skill sets, LoL realizes Pudge's hook is sexy, so they add it as Blitz's pull, but give him an unique kit. LoL is also expanding the genre, with 3v3 and Dominion. Oh yeah, and LoL doesn't have a WTF-mode, which HoN does to my understanding.

Dota2 is a remake of DOTA. Practically the same game, Dota 2 simply has matchmaking and better graphics. And it will soon have Valve's never-failing, TF2 drop system.

tl;dr, Dota2 is an exact copy of DOTA, HoN copies some elements, and LoL does its own thing.
