Space Rangers 1 and 2. Must have, IMHO.
From same studio (actually same people, studio got renamed/reformed/resomething): King's Bounty, there are three: Legend, Armored Princess and Crossworlds, hard to say what is add-on, what is expansion or something.
Fantasy Wars - a bit "niche" game, a-la Fantasy General, so if you long for it, give it a try. Has add-on Elven Legacy (distributed as stand-alone game, yet it is add-on) and mission packs - Rangers, Siege and Magic. Good stuff if you miss old Fantasy generals and minis table tops.
Also Majesty 1 and 2 - indirect control strategy type games. Majesty 1 is old, about decade old, but still delivers. Majesty 2 is sort of remake, made by same studio that made Fantasy Wars.
Gothic, especially 1-2 (sale on Steam, ends in six hours from date of this post or so, so make haste).

Demos to most of them are available at gamershell. Maybe some on Steam.
