hi… sorry to chime in as a noob… been a longtime lurker on here… never felt the urge to post a comment until now.
weird thing is, the 7800 was already said to have 'failed' in the 80's because its library was more or less outdated back in the day.
I do own a lot of recent 7800 homebrews - and I love'em!! - but I find it odd that the vast majority rely on early 80's maze-games or vertical shooters… just like the first generation of 7800 games in the 80's.
I mean, those games are great - but we know the 7800 can do better… OF COURSE I wish the 7800 would get ports in the same vein as the Colecovision (Gradius) or as the Atari 8-bit computers (Bomb Jack, Space Harrier)! Or maybe Crystal Castles, Arkanoid, Tempest, Pac-land, Paperboy or Marble Madness when it comes to (Atari) arcade games. The 7800 gets even less mid-80's games than the 2600 which had its limits pushed with Thrust and Boulder Dash.
So yes, I do have a Coleco envy… no, wait… I love my Ataris and don't want a Colecovision anyway…
