There is also Unigine [1] but that has less community around it than Unreal. I am mentioning it because I think it should be known more. It was started by a single russian dev who was initially just writing online tutorials on various OpenGL and physics stuff (frustum.org). Then he decided to make a commercial engine and started a company. Of course their engine evolved a lot since and they have a team of devs now... - Source: Hacker News / 9 months ago

Give it a good once-over when it arrives for any shipping damage, check to make sure that memory overclocking in enabled in the BIOS since that's sometimes not done by the builder and then benchmark it with something simple like Unigine to make sure it's not running weirdly below the norms (4070Ti should be around 3100-3300 in Unigine Heaven) or you can download 3DMark Demo and it should give you a...

So you consider an engine "professional" if your favourite big PC games run on it? What sort of logic is this? I suppose enterprise-geared engines like UEngine aren't "professional" either because they aren't popular with game developers? Source: almost 3 years ago

Flare is an open source diablo-like action rpg. Source: over 1 year ago

I'm a big fan of Flare, and it was a sleeper hit for me because I didn't grow up with games like Diablo. It's open-source, and while it has a pretty short campaign in the vanilla version, it has a lot of fan-made campaigns and mods. It's not the most engaging game I've played, but it's fun to zone out to while listening to podcasts. Source: almost 2 years ago

Therefore, if a game has to use an off-the-shelf engine, at least make it an open-source engine like FLARE or O3DE. If you're picking libraries, use something permissively licensed, so you don't have to try to negotiate a commercial license to combine something with a copyleft, like recently happened to the remaster of the old Blade Runner point-and-click adventure game. Weird licenses mix together about as well... Source: almost 2 years ago
