I can see where small bits of this remix may fall slightly short, however the key in this is the capturing of the epic feeling. Having played the game recently, I know how desperate you can feel when you are that far in the game.
*spoiler alert, skip to next paragraph if you don't want to see it*
Not only do you have to beat the Robot masters of MM3 but Wily ressurects some of the toughest badies in the Mega Man universe, the bosses from 2, to fight you next. THAN you get to fight in Wily's fortress.
This song captures the pure adrenaline and need to persevere that the game inspired in it's players. Combine the feeling with a solid remix and you get a similarly solid recommendation from me. Well done Gux.
