I am hopeful that the new SC3 game engine will allow a remake of the SC1 original, with some enhancements based on the latest features but also with a keen eye on keeping the game simple and fun as it was in the beginning. All those new unit types do not have to be used, don't ya know?
I enjoyed the heck out of the original game way back when, but deep down it always nagged at me that it was too abstract and failed to capture the historical accuracy essence that a classic WWII game should provide. The SC series has grown and evolved nicely but, as discussed, some of the fun factor has been lost along the way. Also, the community has become greatly fragmented with all the different game versions and forums. Not like the old days.
FWIW, I'm pretty happy with my latest Advanced Third Reich mod using the Global Conflict Gold version. I'm not planning to update it again until SC3 and then I'll see what I can do with it. I also have ideas about an Army-level ETO mod, a la A3R-lite, that should be fast and fun.
