I asked people what their personal favorite indie game releases of 2010 were in the forums; this is a compiled list. Each mention got one vote per person. There were a lot of ties, which is why the numbering is a bit wonky. Minecraft isn’t officially a 2010 game (it hasn’t been released yet and was first put on sale in 2009) but was included because it gained its popularity and most of its content in 2010.

All other games had either two or one votes. Games with two votes were Depict1, Octodad, Arvoesine, Ceramic Shooter: Electric Poem, Sombreros, Towerclimb, Transformice, Ninja Senki, Solipskier, Shoot First, Bit.Trip.Runner, Puzzle Dimension, Joe Danger, and Zen Bound 2. Games with a single vote are too long to list but can be found in the forum thread.
