Compared to LOL, Dota 2 is much more faithful to the original Defense of the Ancients. You won’t find any variants on the classic 5-on-5 map. However, Dota 2 does offer immediate access to all of its heroes, with microstransactions reserved for cosmetic stuff like character skins and announcer voices.
Being the newest of the bunch, Dota 2′s also the best looking. While all three feature visuals clearly inspired by Warcraft III’s art direction, Dota 2′s graphics have a cleaner gleam and shine to them.
Generally speaking, Dota 2 is slower than LOL. While the layout of the map is identical, Dota 2′s is a bit bigger. Actions, like movement speed and casting spells, are generally slower. Also, while LOL allows players to transport back to their home base at any time, you’ll need to have a stack of town portal scrolls handy if you want to get around in Dota 2. On the plus side, using the scrolls can send you to any friendly building, including towers.
