Yet Another Newb Question.

Hii...
I am new to PC war-gaming - totally new. I am interested in military tactics and strategy games, and I am purchasing 'Battle Academy'(1) this Friday. This game is listed on Slitherine as 'Complexity: Introduction', so my question for all you veteran PC gamers is this - what other military tactics / strategy games - at an 'Introduction' level, would you recommend? The particular war or weapons doesn't matter, I just don't want to jump in over my head and find myself overwhelmed and discouraged, as happened to me years ago with board games. Thanks in advance and my apologies if this type of question comes up frequently.

Thanks!

I didn't find the right solution from the Internet.
