10 Jaw-Dropping Video Game Success Stories You Need To Hear

3. Castle Crashers

One of the highest selling titles on the Xbox Live Arcade, you might already know five-man development team The Behemoth for their work on 2D blaster Alien Hominid, or from artist Dan Paladin's phenomenal work on Newgrounds flash games.

For Castle Crashers they took the simple, Diablo-esque approach to raiding through an environment with a group of friends and made it as instantly-fun and rewarding as possible, smashing sales records left right and centre and becoming a regular staple on the game library of anyone who owned an Xbox 360.

As of two years ago Crashers had seen 2.6 million downloads, and that's with a record-setting 110,000 units in the first three days. When you factor in just how much bigger the indie scene has become since 2012, and with Behemoth's coding of ports to both Steam and PS3, the mark this arcade classic continues to make is just amazing.
