RS:122 WW1 Tannenberg Eastern Front

After I tried ISONZO, I added Tannenberg and Verdun to my wishlist. For whatever reason, Tannenberg and only Tannenberg is on sale for $4 at the time of this stream, so I added it to the collection. My understanding is all the games are pretty much the same, just different maps, weapons, nations, uniforms, etc. There should be some graphics that are better with the newer games, but whatever. I'm playing this for the first time and I'm sure I'll love it.
