I have Dorfromantik and play it occasionally. It is very relaxing, which can be nice. And very, very simple. So simple that I sort of hesitate to call it a game. There is some sort of scoring, depending on the mode you play. But I always pretty much ignored the scoring and didn't even want to try to understand how it worked. It is fun just to make your little town, forest, river, train track, etc. So it is more like model railroading to me than a videogame. But highly structured and guided model railroading.
I am also uncertain but it does seem better than the old 2 layer/level system. I don't like limiting the choices but I do tend to only use a few weapons.
Back in the day, around the time of CS 1.6, some co-worker friends and I would have LAN parties. This was when everyone still had CRT monitors so we had to be careful not to trip circuit breakers.
Rogue Tower - Steam description: Rogue Tower is a tower defense game with roguelike elements and a continuously expanding path which you can influence. Unlock, build, upgrade, expand, defend.
I've enjoyed unlocking all the cards and completing the 1-path (simpler) mode. Now I'm working on 2/3/4 path modes and finding them much more difficult. Uncovering levels of strategy I didn't know existed in this game after simpler mode. Surprisingly complex for a tower defense and very interesting.
I went on a binge with that game recently. It is amazingly deep, I never got near all the possible ways to play. I was mostly enjoying getting my ass kicked by the computer in multiplayer.
Fun game. I'll probably get back to it eventually. Seems like it will be around forever.
ETA: There's a pretty large AOE2 community on Reddit (still? IDK?) and frequent vids on YT. I remember some very detailed analysis vids on YT when updates came out. And competitive is still a thing too.
