Unity3D

I'm actually pretty impressed how it's come along. Take a look at this mario remake:

Super Mario 64 Full Playthrough

I haven't downloaded the game, don't plan to (looks like Nintendo forced him to stop anyway), it's not a full game but still made by one guy. I see room for a ton of improvement on the texture art, but gameplay wise it looks pretty good. Sound is good too.

I have some games using Unity3D, but really lately I came across the long dark that really impressed me with all of it's recent development. It's not a one man team, but they have like about a dozen people working on the game. It's a lot of progress for so few people.

Then I came across Star Break this weekend. This too is a Unity game, and looks really great. imo needs more content before I pick it up, but otherwise a solid game there.

Then I picked up Ravensword: Shadowlands on Android a few years ago, an Elder Scrolls type of game. Not so great on the PC release later, but it was ground breaking for Android where not even AAA studios were really touching it at the time, and since they have now - we mostly see ports.

I think the only drawback, which is no big deal for the indie devs, is that it's using mono which is still stuck on an older version of C# for the scripting, which isn't bad for the vast amount of tutorials made to use it with Unity. But otherwise wow the games coming out of this run so well even on slower computers/laptops and little devices.
