Panzer corps was a great game, so improve on what is already working:
1. More useful factions: All the minor factions and even major ones like Italy or France lacked a lot of units they actually had in real life. Giving these factions a larger amount of units makes them interesting to use for different scenarios. This in term allows a wider range of content.
2. More different graphics: PC1 had way too many units sharing graphics and looking the same. Unique graphics for al of them would be an amazing improvement.
3. Smooth zooming: PC1 had only fixed levels of zoom. Why not improve this and allow fluid zooming from 100% all the way out to the strategic view. A lot of rts games have this, and it would be a welcome upgrade to this game.

Thank you, and looking forward to this sequel
