In no particular order:
Toe Jam & Earl - The definition of fun, and manages to feel almost new even though i have finished it like 100 times since 1991.
Revenge of Shinobi - People seem to prefer Shinobi 3, but for me this one is the best, also i think the music is not only better than 3 but also sound way better.
Strider - A kickass non stop ride.
Golden Axe - It was like having the arcade at home, and still is brear coop fun.
Sonic the Hedgehog - A masterpiece and still the best Sonic for me, and the only one that i really like.
Desert Strike - Madman must have been stopped.
Mercs - Although one player only it has the original mode that is awesome.And i love those top view shooters like this and Jackal on Nes.
Castle of Illusion - Amazing game and still best Mickey game for me.
Streets of Rage - I,m in the minority but this is my favorite of the series, music is the best of series
Thunder Force III - Same thing, people usually prefer 4, but i think this one is the best, also one of the best ost ever.
Also hi retromags, and i have to say that i'm deep thankfull to all the staff and everybody that helps this wonderfull place.
