depends on what consol you plan on playing. You can play old games via an emulator and roms.
Master system-----Ninja, R-Type, My Hero, Ghouls and Ghosts, Alex the kid enchanted castle, Wonder Boy 2 is pretty much impossible
Loads more old games I cant think this morning lol
Playstation----you could do Heart of Darkness.....veerrrrrry hard game, Ooze....another hard game, Crash bandicoot games getting all gems and relics (This requires you acing the bonus levels too)
If you want more let me know lol[DOUBLEPOST=1429252967,1429252856][/DOUBLEPOST]OOOO!! One on steam I'v played which was fraustrating in places. Its called "You have to win the game" took ages to get through that game and complete it 100%
Omg I've watched people play that! Dear God it looks hard and terrfying!!! The AI being smart is even worse! BahahahAlien: Isolation on Nightmare Mode will make you want to commit acts of revenge against the creators of the game for making itIt's the most difficult game I can think of that I own or ever played. It's not the dying so much as the restarting that will get you p****d off because you will know you are screwed and your life is over before you can do anything about it. I'd say wait until the game is on sale though. Like under 20 bucks because when you beat the game on your first time on Nightmare mode you will most likely NOT want to play it again and/or will regret buying it.
You are defo gunna need to focus on the old consols then including the ZX spectrum. Games back then very rarely had passwords or even the option to save. So to complete it you had to liturally be a master. i dont even know how I completed half the games as a kid now when I play them again.This is an absolutely fantastic list. Thank you so much. I really want to just play the hardest games I can find. I feel like I've been slacking as a gamer with all these easy titles lately!
