Hey Tom,
Indeed, welcome! I'm the designer of the game, so I'm of course biased with how easy or hard it is to pick up and learn. I imagine you'll do fine, though, as this game tends to skew older in its fanbase. Most fans do seem to be in their mid to late 20s, or early thirties, but we have quite a few folks that are in their fifties or sixties who play. A number of them are also fans of the matrix games titles, and posted about this game on those forums.
I'm in my late 20s myself, but a big part of the reason I created this game was to be able to play it with my dad, my uncle, and one of my uncle's colleagues. The colleage is about my age, bt my dad is in his late fifties and my uncle is in his late forties. In a lot of the games we played in multiplayer over the years, my dad and uncle were at a disadvantage because they weren't super fast clickers on the mouse. They're both very tech savvy, very much into science and engineering, but that manifested itself in strategy games as a desire to sit, think, plan, and execute. Having it be a test of reflexes just wasn't part of the equation for them, which was a frustration with most rts titles. So, with their constant feedback and ideas throghout the design process, ai war was designed to be a title where we could play together and all be on equal footing withoUt the reflexes thing being an advantage for me and the colleague. Not to imply that my dad and uncle have bad reflexes by any stretch, just that they don't even think to exercise those reflexes during a strategy game. So, in the end ai war turned out to have more in common with chess than starcraft, which also suited my own tastes well.
Hope you enjoy it! The tutorials should give you a great feel for it, and the wiki is chock full of other articles and information if you want. Thanks for your interest!
