so I've been playing Trilogy on Vita off and on lately and it aged really well, it's pretty great that it managed to archive those games so you can play them long after they've been pulled from all the app stores
It must be a nightmare for anyone trying to keep up with the whole series. The only two console releases were Trilogy and Star Wars, leaving like half of the series to the whims of the App Stores. I'm sure some zoomer someday's gonna release a megawad-style compilation with all of the levels ripped out of Android versions and put into one huge game in an effort to preserve them.
