I'm sure you all know theres thousands upon thousands of units, just to many to take the time and research them. Well, i've gotten bored and started. In about 3 days, i've researched exactly 1000 units. Most of them are nothing or crash sc, but theres only a handful that are cool. I also plan to keep researching untill school starts.
Keep in mind - I used Starforge. I was zerg the whole time. There was only 1 other unit on the map (Enemy Marine), it was on Jungle terrain. Some units that crash might be able to have their building exits blocked, thus stopping the crash.

It goes like this : Unit# / How it appears in SF - Effect (Notes if any)
