Tower of God
 

For those of you who haven't heard of it, it's a Korean net comic about a tower that grants wishes to those who ascend it. My lame description makes it sound kinda fruity, but it's actually a really neat story. Basically, imagine taking every hero or villain in any fantasy/scifi/action story/game you've ever seen or played, and throwing them all into a situation where they are pitted against each other. It often delves into the psychological aspect of battles/fighting, and is kinda unique right now in terms of manga/manhwa. In this universe, there is always someone more powerful; despite the massive power a certain character obtains in the second season, he still is comparatively weak. Anyway, enough of my rambling, go check this out, it's translated on most scanlation sites, although I preferhttp://mangapirate.net. Let me know whatcha think.

This sounds pretty cool :D

I actually really enjoyed that manga. One of my top 5!
