I hope you don't mind that I've started a thread about your next featured game, Ferg. I just wanted to offer some very brief, potentially useful feedback: Tanks, but No Tanks is "heavily inspired" by a 1981 Namco arcade game (distributed over here by GamePlan) called Tank Battalion, in which you're engaged in a multiple-tank firefight within a maze, while protecting your base along the southern border -- just as in the ZiMAG game. Nothing I've read has pointed out this comparison, so maybe I think I'm clever for noticing. Of course, one never reads much about ZiMAG games in general!
Quite fond of the Zimag games for some reason. I enjoy two of them and enjoyed collecting them - only 4 carts in their library but all fairly rare. Took a good while to get hold of the instructions though (I don't collect boxes). Like the art style of TBNT too !
