Space Run

Space Run blends two genres that previously haven't really been mixed: tower defense and real-time strategy (RTS). Tower-defense games, in which players set up turrets and defenses to protect their territory from oncoming attacks, are usually treated as casual video game fare, meant to be easy to pick up and play. RTS games, meanwhile, are historically known for being only for truly hardened veteran gamers who are willing to devote their entire focus on building and organizing in-game assets for combat. It's this refreshingly unique -- and frankly unexpected -- blend of gameplay styles that makes Space Run enticing to even the most cynical and jaded player. It makes the game a bit less universally appealing than a straightforward tower-defense game, but it also introduces sophisticated and rewarding gameplay styles to an audience that might usually turn away from games with a similar structure.

The game also has a good level of "replayability" because of the score-based nature of each mission. Players are always encouraged to redo previous missions with the hopes of getting higher scores. Ultimately, this game achieves something few titles are able to: It introduces a completely new and unique gameplay style. Those willing to overcome the tough learning curve will enjoy the refreshing and fun experience Space Run provides.
