Quoted from Frax:Eh, I'm selling Iron Man and Demolition Man to get Ultraman.
I just can't decide which is the best man apparently.
The answer is always Lionman.
The choice for me would be to sell two games to buy one, but that is because I'm space limited, I have projects that I'm not working on because I don't have space to put them. I'd probably try to keep the Spiderman and sell something else though.
