I went through the comments in
Ikinz's thread and counted the number of times people mentioned a given reason.
I considered Zero-K and Spring as one entity for this count since it's hard to tell which factor is for which.
Supcom and TA We should definitely mention those games in our steam description!
Flat Tech Tree This is pretty cool! The flat tech tree is our n.1 unique feature. How can we show visitors that it's a good thing?
Unit Variety Tough to sell! We can't just claim our units are unique. Everyone claims the same.
Community/Active Playerbase We could place a status panel image in the steam description, with the number of games running. I'll have to check whether it's technically feasible.
Development/Open Source We can place a Github button in the steam description.
Physics Easy to show in trailers.
Terraforming Easy to show in trailers and screenshots.
Lots of Units Easy to show in trailers and screenshots.
Damage Model Hard to tell the benefits without a lengthy explanation.
Planetwars Easy to describe and likely impressive in screenshots!
Nice Explosions Hard to make a trailer without one!
