Mostly asking because I've never used these before due to never needing to. That, and I have a few old disc based PC games that I'd love to be able to straight up boot without the game disc. These are games I could just pirate, but I figure I already own them in disc, so I'd rather see if there are any reputable places with no-disc patches. The places I've looked in the megathread don't have what I'm looking for.
Closest they have is either a link to the game on another platform in the case of My Abandonware due to it being sold, or a link to just straight up pirate the full thing in the case of Magipack Games. I've also done some digging on the Internet Archive but have yet to yield results (probably because I suck at finding things there). Still gonna keep looking there, but any helpful info would be much appreciated.
I don't think I can share the game names, even in DM, due to the rules here, so site mainpages are my best shot.
I don't see many people ever really talking about them at all outside of fans, but Krosmaga and One More Gate from Ankama.
Krosmaga is a deck builder autochess like game (with something like 9 or 10 different classes/dieties with different abilities to build around, alongside a bunch of non-specific cards any class could use in their deck). Place summons/spells to protect your Dofus (dragon eggs, to simplify what they are) and destroy theirs. Matchmaking is either play against computer, who randomly selects class and gets default deck, or just flatout random player. Don't think there's any selective matchmaking, sadly.
One More Gate is a short enough roguelite game where you accidentally destroy a portal and have to fix it by beating bosses in new areas, usually after multiple failed runs. Has meta progression, which I personally am not the biggest fan of.
