Aight I got one I think is oddly specific, and another that's just odd.

I'd like Starport: GE but as a fantasy RPG theme, instead of ships and colonies it's classes and villages, work the reputation system into a good/evil alignment and change some gameplay.
Not sure about this one but I would like a hub system, only thing that comes to mind for me is realm of the mad god, allowing you to go from one server to another with limited items.

On that note I should probably try to play starport again, has been a number of years.

Other than that, maybe a 1v1 auto battler? A mix of part of a dream into hazy dozing in and out put an idea for an auto battler where you have four incubators and six chicken eggs and each incubator changes what type of chick hatches, where they then fall into the arena to start combat. The choice of incubators and which ones your remaining two reinforcement eggs go in to I think would make an interesting head to head game.

An actual follow-up to Tribes 2.

All the sequels (Vengeance and Ascend) pale in comparison, and the rumored sequel (Deadzone) is all hype and vaporware at the moment.

I like location based games, like Niantic has done, but with much less backstory.

An updated version of Ubik.

Planetside 3

A business sim that models a country and you can run any business you want, and see if you can build a successful business. I'm talking a sim that models every other business, every city, every street even. The whole economy. Way beyond what's realistic for sim games at present.
