I wonder why real-time-strategy (RTS) is dead outside of the StarCraft 2 e-sport niche. RTS used to be the best selling game category around 2000.
Mostly because designing for e-Sports has a massive effect on options and creativity of an RTS - keeping the game balanced and fair for competitive play comes with a massive tradeoffs in creativity, faction diversity and player options (especially if the developer does not have large amounts of time for balance testing). And since for some reason everyone wants a piece of that pie the RTSes have become a bit... bland…
I play from time to time 10-15 year old RTS games like Age of Mythology and C&C Generals against bots in SP on random maps. For me it's a lot more rewarding playing a real RTS than going from bottom left to top right in e.g. League of Legends.
RTS is great as it is about planning economy (buildings, resources) and planning war strategies. RTS aren't that hard to grabs', a new player can learn it in 10-15min, but a game can last up to about two hours or more - and one cannot watch TV while playing or something else aside with a real RTS.
For some reason it seems a newer wave of players favor repetitive gameplay with instant rewards that may have familiarity with gambling mechanics (getting hooked) over freedom and choice.
I would pay premium for a new RTS game that delivers the old gameplay mechanics and has a more realistic theme (like C&C, Age of Empire - and no aliens) with a good highend graphics and physics game engine.
