You might like some of the games at matrixgames.com and slitherine.com because they specialize primarily in turn-based strategy/war games and have a ton of them. However, while some of them are 'pick a scenario and play', others are hugely complex with full production, logistics, research, etc. The John Tiller's Campaign Series games and Strategic Command games are pretty playable, Harpoon Ultimate if you like naval, and Field Of Glory if you have interest in the ancient/medieval eras.
