Thank you, GOG, for putting "powered by Dosbox" on the store page for this game. I tried the game, tried tweaking the settings both in-game and the Dosbox settings, but it just doesn't work. You can drive a giant machine around and shoot at stuff, but actually hitting things is another matter. Accomplishing mission objectives is practically impossible. If it ran better it would probably be a decent game, but it's hard to tell. Bottom line: this is not fun.
If you do, all the Galley units in the game will acquire every special, including weapon immunity, flight, and the ability to settle towns. I don't recall having this bug when this game was new! Even if one of the AI opponents casts Raise Dead, your game is boned. I love this game, but I can't stand this bug.
