By chance I saw just how high Fallen Hero: Rebirth is rated and went to check what the highest rated games on Gplaystore are:
CoG: 4.8 (two games)
Choice of Robots with 2291 ratings
Versus 2 with 347 ratings
HG: 4.9 (three games)
Great Tournament (27199 ratings)
Wayhaven 1 (2869 ratings)
Fallen Hero Rebirth (1550 ratings)
Gratz to the authors.
I think both Tin Star and Gun of Infinity for HG with 4.8 deserve mention as well .
Especially these 2 games are immediate purchase without free demo … those who download them are confirm paid download 
True.
I’ll change the list to the top 5 later :3
There are actually 2 more games with a score of 4.8 and they both have immediate purchase which are:
A Study in Steampunk and Samurai of Hyuga 2
Yeah…
You are correct
