Almost all systems here have a top 100 list voted by the readers, so, why not the Turbografx? Everyone knows how this is done. You can vote for your Top 10 Turbografx games, and your Top 5 Duo games (as there's not as many) and I'll count the votes.
My top-10 TG list is:
1-Military Madness 2-Dragon's Curse 3-Splatterhouse 4-Alien Crush 5-Ninja Spirit 6-Dungeon Explorer 7-Blazing Lazers 8-Bloody Wolf 9-Legendary Axe 10-Bloody Wolf
And my top Duo list is:
1-Rondo of Blood 2-Lords of Thunder 3-Gates of Thunder 4-Buster Bros 5-Dungeon Explorer 2
