What are you talking about? Chess is the ultimate strategy game. Strategy didn't implement itself with airplanes and resources. Strategy has existed since the beginning of time. Strategy is using your mind to thwart an opponent.
If I'm black in chess, I'll go into the game with a defensive strategy. I'll adjust my tactics to fight off what white is doing, but I'll try to stick to my main strategic element, which is being defensive and waiting for white to make a mistake or to overlook a subtle attack that I've created.
There is more strategy in chess than any other game ever created. There are more ways to play chess than any other game. There are more outcomes to a chess match than any other game. In Age of Empires or Warcraft, it's all gather gather gather, create create create, attack attack attack. There are little nuances of strategy, but I would say that there is no more strategy in WC3 or AoE than in games like Battlefield 1942.
The truth is that it's easier to master an RTS than it is to master chess. Chess is taken for what it really is by people who have knowledge of it, and it's taken for a silly board game by people who only know how the pieces move.
Anyone who says what you've just said has no idea what Chess is all about.
Heck, Football has more strategy than any RTS games on the market. Actually, I think the only real way to create a game with major elements of strategy is to make it turn-based. The emphasis needs to be put on strategy, not super quick resource gathering. To me, that's not strategy, that's moving and mouse and pressing hot-keys really fast.
People are going to hate me for this post. Ohwell... =)
