With my group I try to show off other games and they are thankfully accommodating. I try to play some form D&D and then after that something different like Cyberpunk or Vampire or Paranoia etc.
About the time Dragonlance 5E came out I swore off DMing 5E until 5.5E came out and hopefully fixed some of my issues with the system (Yeah yeah hope for the best, prepare for the worst).
We instead played some CoC, AD&D 2E, some Shadowdark, and some Cyberpunk Red. Someday we will play some Star Wars which has been requested (isn't a new version coming out soon?)
CoC was a disaster. 2E and Shadowdark went fine though while most liked the ramped up difficulty they did not like feeling less powerful compared to 5E. Cyberpunk was okay but like CoC, it just isn't some of the players "thing".
Well, I wanted to get them back into their comfort zone and I had recently picked up the 3rd party adventure Rise of the Drow, so yeah back in the saddle for 5E... with some houserules. Like no multi-saves for things like turning to stone, it's one and done and a couple others to give it more AD&D feel.
I asked them when making characters to think more like Lord of the Rings and less Sponge Bob, so the party is a Warforged, Goblin, Tabaxi, Human, and Elf.
Anyways, to the point. Several times 3 of the 5 expressed "I am glad to be playing D&D again." Which kind of hurt my feelings. Which I don't know if they mean 5E or just to be back to "D&D like 2E and Shadowdark". Although one of the teens did say "I like this and 2E" Which did make me feel good.
I noticed they are back to playing in "5E mode" though. Rush into a room, not worry about traps or monsters due to ease of healing and/or a plethora of HP. As opposed to 2E and Shadowdark where they were more cautious. Maybe once they encounter a Basilik or something they will remember they aren't immortal.
Overall, I as a DM have been learning to try not to fit a square peg into a round hole. They (we) love D&D and trying to get them to play something wholly different like CoC and Cyberpunk might just not be for us. I'm not going to stop having us play OSR on occasion. Thankfully it's "close enough" to 5E, I may use Shadowdark or C&C for a Megadungeon at some point. But yeah I'm learning to "let go" when it comes to my expectations of non-D&D games because I want us ALL to have fun and as long as they are having a good time that should be enough for me as the DM.
I'm not giving up on them liking The One Ring either. Come on Moria book! Ran a campaign once but I didn't get the reward system. After like 2 adventures the party was pretty decked out it seems just from level up rewards. IDK.
Oh and I want them to try Avatar tLA, but so far that idea went over like a lead balloon. Plus the system seems pretty different to what we all used to. Oh well, fun to read anyways.
But yeah, guess I'm not done with 5E and that's not exactly a bad thing as I can fine tune it while keeping them happy and having fun.
