For me it was a series of an unparallel story telling. Nothing even close amongst the titles available nowadays. Furthermore great game mechanics, simple and yet very demanding with a good difficulty level. All that sprinkled with a nice and somewhat grim sense of humor. All maps were by far not straightforward and quite diverse with limited resources at hand. One juggled amongst a couple of unit types with very well defined specialisations, sets formations and tactics to face particular types of enemies. In this aspect I must mention the that these games one could play as RTS or in some more tactical level with commands assigned during a "pause-menu screen". Yes, the commands were not disabled :). If you like RTS here you go. If you like tactics use the pause. Just brilliant :) These are also one of very few games that I have played more than two times and two is for me the usual top of my patience-Nostalgia level.
I know the graphics is somewhat vintage but should still sit well amongst the pixel-freindly customer base. To my understanding the games were made for Windows 95 in mind so a dosbox wrapper is no go and the conversion will be a challenge. On top of that these were using some weird 3D animation approach for units that was not easy to adopt to modern PC-s but GoG has managed far more difficult taks. Please bring this game series to GoG :)
