If teens and adults were impressed, imagine what a 10 year old me felt when he experienced games on an Amiga 2000 back in 1989 with computer monitor.
Though when I visited the guy who had it, he usually avoided getting us to play adult or complex games. So I mostly played arcade ports or games like Ducktales, Fiendish Freddy, Batman, Xenon 2, Zak McKraken, Loom,Indiana Jones and the Last Crusade, Prince of Persia, Shadow of the Beast, Ghostbusters 1 and 2, Defender of the Crown, Beach Volley, Top Gear, North and South, Warlock's Quest, Mike the Magic Dragon (my avatar), Barbarian 1 and 2 etc
Favorite arcade ports were Bubble Bobble, Rainbow Islands, Shinobi, Ninja Spirit, Ninja Warriors, Dragon Ninja, Wonder Boy in Monster Land
Also painting on the Amiga was very funny.
But sometimes he'd play or demo some more adult oriented games and I felt even more impressed and shocked. Elvira 1, Weird Dreams, Lost Patrol and some sex games like Party Games.
This was really the future of video games. But I also played on NES, Gameboy and arcades too.
There is one game I am looking for:
Only clue was reading back then a video game magazine and it had a naked female elf on a pond staring scarred at you. Must be an RPG probably. If anyone has heard about that game, I'd be grateful.
