Here’s a great space shooter with lots of upgrades: Enigmata. Use the cursor keys to move around and the space bar to fire. Press X to speed up, and C to enter stealth mode (though I did well without these). Kill the bad guys, dodge their shots (and the Xs), and pick-up upgrades to heal and make your weapons more powerful.

I wasted half my childhood playing 1942 for 25 cents a shot, and while this game doesn’t quite give me the feeling I got in the back room of the Pizza Hut, the upgrade system gives it an entirely new dimension. In my opinion, the upgrades are a little too complex–you’re limited in the amount of upgrades you can have enabled, which means you have to waste time doing inventory management. Many of the upgrades only improve your performance by like 5%, so you won’t even notice them.

I got 435,780 my first time through before I died. It’s nice that you can save at the end of every level, so you don’t have to repeat levels like you do in Super Mario Bros for the Wii. I hate you, Super Mario.
