Although I have finished many games and now spend most of my time working on Unity assets, I've also made lots of interesting prototypes along the way that may never see the light of day, so here they are.
Realtime/Turn-Based hybrid space combat game.
I had an idea that maybe you could combine turn based combat controls into a realtime space combat game, so I made this prototype. It also featured a dialog system with a dog, for some reason...
UI System.
Before the days where Unity had their own UI system, you had to roll your own, and so I did. I eventually released this on the asset store under the name "EVO", but I since depreciated it because there's no point in competing against Unity's native UI.
3D Modelling.
Before I learned programming I learned 3D modelling, UV mapping, and 2D texture creation. These skills have now been far surpassed by my programming abilities, but they still come in handy when I need to test or tweak something.
Ocean Rendering.
Who doesn't attempt to do ocean rendering at least once?
Low Poly FPS - The Platform.
This was one of my first Unity test projects. I released this on Kongregate, but I guess you need to release an idle game to gain any traction there.
Tower Defence.
Back in the day when these were popular on Flash, I made this. I think I released this for free on a games portal somewhere, and I only just remembered I made it when going through my old projects, neat!
