I'll look for some of the RaR SGs.
At one time, several years ago, I did look at RaR. Not very deeply, though. And what I saw reminded me of a real time strategy game I downloaded the demo of (Age of Empires?). And what I disliked about that game (aside from the clock ticking in the background) was the minor upgrades in the technology.
For instance, in C3C, the upgrades are pretty broad. Swords to Maces, Maces to Muskets, Muskets to Rifles. In this game, the upgrades were smaller. Maces did not upgrade as in C3C. Instead, the upgrades were to better armor, better helmets, better weapons for the Maces. I did not care for that kind of detail.
And what I saw in RaR when I looked at it, reminded me of that. And I wasn't willing to learn anymore.
In the RaR games we have here, are there one or two that explain what is different and how that affects the game?
