Got Golden Axe from that first bundle
It's short, but man is it addicting.
Although I have to say the final boss in the game (it's the Genesis version, so it's Death Bringer iirc) is freaking cheap! Two invulnerable skeletons and an attack that shaves off up to three(!) bars of life! Death Adder was bad enough with two skeletons and an axe swipe that takes one bar of health away!
Still gotta play Jet Set Radio and Hell Yeah.
I'd recommend the second bundle for at least Streets of Rage 2 (apart from the fact that, well, free games).
