Either you like Galaxy Fight or you don't, as simple as that.
IMO, and despite what most ppl say, it's a nice game, but if you don't have any 2P competition, you should verify first that you are a determinded player - GF in 1P is tough as nails, no matter what difficulty level you choose. The CPU is very cheap, and the fact that there are no level borders (the levels scroll on endlessly) and the different gameplay features (focus on dashing combos/attacks) doesn't make it any simpler.
Graphics are a mixed back, personally I like the trashy, dark and gritty look, but that's just me. The end boss (Felden Krais, what a stupid name...) looks awesome in my eyes.
The characters are quite cool, except for the robot G.Done (which you will soon learn to "love" as a CPU opponent). My fave charas are Rolf, Kazuma and Roomi... because GF is a Sunsoft release, you will notice some familiar things, that is if you know Waku Waku 7... WW7 is much more refined than GF, but both games share some elements.
Like the others said, if you can get it for a good price, you should pick it up and give it a try, but don't expect too much return-of-investment if you are going to sell it again...
