I am also playing this game for 7 years lol. Best game ever. Give it a try!
EDIT: make sure also to check the forum!
Years ago Cavedog's Total Annillation was my best RTS game I ever played, superior to many later games.
Only RTS game I consider superior to TA was Supreme Commander by original creators of TA. SC1 got older, SC2 was not so good, I played SC1 with 3rd party launucher Forget Alliance Forever, but large battlefield games were not working correctly on modern PCs.
Meanwhile I played with Spring as part of my TA obsession, before SC1 came out. Somewhat I missed Zero-K mod for Spring.
I am happy I found it 3 months ago - on Steam. It is a great game. Superior that most contemporary games, more complex than Ashes of Sigularity etc.
First game you can reshape your map!
Chapeau bas, devs! Great job.
