Do you remember Crimson Wars? Few people do these days.
Crimson Wars is a 1999 RTS game that has largely been forgotten. Practically no official references to it exist online anymore, save for some press releases that mention it in passing. Some gameplay videos do exist, but dig deeper than that and you’ll find nothing of substance.
Is it a great game? Probably not. But I do have some nostalgia left for it, and I also have an unhealthy obsession with digging up old, obscure things.
