yea i'm all up for browser games i have nothing against them, it's just when you're trying to remember what modern game was hardest for you, nothing comes up from the 360, PS3, Wii, ect. unless you're going to use a higher difficulty setting as your pick, or at least some sort of reboot of a classic game like Megaman Maverick Hunter X or something like that, so your best option is to pick a game that isn't on those platforms but something you can play on the computer that you don't even have to pay for, yea there are still a few difficult games regardless of a difficulty setting like what you said Limbo, Demon's Souls, and DKC Returns, or like what i said Bionic Commando but when you stop and think it's a bit hard, i mean back then it was easy to pick what game is hardest because you have a lot to choose from like Zelda 2, the Ninja Gaiden and Castlevania trilogy, the Megaman games, ect. i mean i don't know about you but i can only think of 6 modern games that give me a classic style challenge regardless of a difficulty level
