I also don't think RTS is dead but the category has been stale for some time. I grew up playing Age of Empires 2, and the game still has a healthy player base with regular new content being added. However compared to the turn of the century the pace of innovation has definitely slowed down.
It's nothing like "pure" RTS like starcraft where everything is actually real time. Their 4X games have: speed control, pause, turns (days and months, depending on a game and action). If you remove ability make turns simulatinusly and make a single turn into a day - not much will change in gameplay other than it will take longer.
> 4X (abbreviation of Explore, Expand, Exploit, Exterminate) is a subgenre of strategy-based computer and board games, and include both turn-based and real-time strategy titles.
I am not interested in 4X games.
