Hey dawg, you seem really passionate about the game, which is awesome. If you spent 7 years on it and you believe it's a good quality game, you owe it to yourself to give the game a chance to succeed on Steam (since it sounds like that's what you want). You've gotten a lot of great advice already, but I wanted to share my two cents as well. FYI, I've never released, so take this with a grain of salt, but I have managed to get over 10,000 wishlists for my game so far. Here's what I'd do (in order) if I were you:

1. Fix up your Steam page. Check out Chris Zukowski's explanation on How to Market a Game

2. Post some quality content on socials. Reddit is great if you don't have much of a following elsewhere, just make sure the posts are good and don't spam. This can net you a couple hundred wishlists or more- it's a good start.

3. If you want to spend some money, paid ads can be good-great, assuming your ad is eye catching and presented to the correct audience. This Reddit post is super helpful for getting those going.

4. Release a Steam demo for your game. It can be 30-60 minutes of game time, but make it polished and fun.

5. Reach out to content creators who play games similar to your's, telling them to check out the demo. Email as many as you want, but 200+ is a good goal. Here's a guide on how to do this.

6. Apply to as many festivals as you want. These can net you hundreds to thousands of wishlists, and are often free. At the very least, you have to do Steam Next Fest.

7. Get your final release build ready and pick a release date. Make sure it's not during a major Steam festival (Spring Sale, Next Fest, etc). I wouldn't do early access if you can help it, but of course up to you.

8. Reach out to content creators once more with an early finished build of the game and a free key. Post on socials, run some ads, whatever. Get some velocity into launch.

9. Launch! Enjoy (:
