The simple addition of an RTS Use Map Settings (UMS) toggle helped kick off entire genres, including tower defenses and MOBAs. There was a time when the former genre was king, a golden era, if you will. But in recent years it faded into the background to make way for the next big thing.
Every so often a developer gets it in their head to bring it back, and I'm glad MiniVisions did just that to craft Aegis Defenders.
