I haven't played 5 or more games released in 2008-2009, but here's my Top 5-
1. Cave Story (It shows since I'm on these forums more than the others I go to...)
2. Mushroom Kingdom Fusion (I doubt I could explain how epic this fangame is...)
3. Eternal Sonata (Combines elements from other RPGs, yet it still turns out to be awesome.)
4. FATE (By WildTangent, a rather fun dungeon crawler, & it's easily moddable, too!)
5. Halo 3 (Some bull [expletive] like how the Hunters can reach & hit further than how far they swing with their melee attacks* kind of ruined the experience for me, but it's still an amazing game.)
*I can't believe nobody has a video of this issue on YouTube, yet... Not like it would get high ratings, anyway...
By the way, doesn't this thread belong in the Gamer's Lounge? I'm guessing the only reason it stays here is because it's trapped inside The S.P.O.T. subforum...
