Hi. When I was young my dad installed some sort of platform like steam, where you could play any game from there, but only for 1 hour, because they were demos or free trials. One game that I can certainly remember being from that platform was thinktanks. The game I am looking for is about ww1 planes. I remember you could play either as allies or as germany. Another thing that I remember is the map from the first mission from the allies (roughly).
Any help finding this game or other games from this pseudo-platform is welcome.
