Nice. I guess you were already an RTS fan?
That's right! RTS and RPGs constitute most of my gaming history, so this was a great find.
but the strategy genre has declined so much
True. You can't imagine (or most likely, you can) how disappointed I was after finishing the game, learning that the series had gotten two sequels, and later that neither of them were "traditional" RTS. Whatever their merits might be (and I'm sure that they are pretty good games on their own right), being able to build structures and the macro aspect of the gameplay are part of what I enjoy the most of these games.
Luckily for me, the benefit of having such a big backlog of games past that I haven't played yet means I'm always discovering gems like this
Cheers!
