I've always enjoyed platformers, but with their popularity rising in the indie circuit it seems the vast majority of these new platformers rely on the whole "it's nostalgic and nostalgia is cool" thing and present so little else beyond a generic game. Then many of the others try to be artsy and while some like "Limbo" work, the rest are just try hards with weak concepts.

Giana Sisters is one of the first new platformers I've played in awhile that actually feels like a well made solid and professional game and more than some artsy twist to an old genre or a nostalgia reliant paint-by-the-numbers game. This game is almost Sonic like in some respects and is easily as polished and fun as any Sonic or Mario game ever was. If you're a fan of platformers, particularly the old school Sonics or maybe Earthworm Jim and the like, then I couldn't recommend Giana Sisters more.

Review for Luckbox:

Herp Derp! Fun game! Derp!

A somewhat clunky and incredibly difficult shooter that will really grow on you if you give it a chance. Rather than linear level gameplay like the L4D series, KF presents a wave survival format and open maps with far more challenging and deadly zombies to go up against. Add to that the need to level your class skills, the importance of team composition, the lack of UI crosshairs (you need to aim with the guns actual sights), and you get one heck of a challenging but rewarding game experience. The learning curve is huge and starting at level 0 you will die a lot (even max level people die alot), but it's worth it as the game is really fun and challenging once you really learn it.

Not a great game if you prefer to solo though, so keep that in mind; you need to play this online (there are plenty of servers out there). Also a great game for achievement fans as this game has a huge array of achievements to try and earn.
