When they don't wish to keep track of things, then cut on the golden treasure in half as they don't need it for gear. Don't permit any magic items to be sold, aside from scrolls and potions. And, if they need something while out adventuring, roll 4d6 under your Wis to RS gold see whether you believed to purchase it and bring it. Great luck together. This seems like the thing to do. 5e appears to check all your players boxes, and trying to shoehorn them in a system may not go over well. The group I DM for has zero interest in departing 5e, therefore I had to find a secondary group to receive my OSRS jollies from. But if I reach the stage it is old-school or bust and you are at, I'd lay down a similar law. "If you want me to DM, we gotta play X system cause that's where my pleasure comes from. If you'd like a different system I will help share some funds or make you installation, but someone else is going to conduct that game."
They may come about. After 6 weeks of just not fulfilling nothing but board games, a few of them confessed they were being covetous. They still want a"super hero" style game however. I stated"1e or older...or you operate it", and finally one of them did. Then he apologized after his match as he realized just how much work I had placed in. But as others have said, you will have to find another group.
If your players do not enjoy RuneScape you want to run there's no point trying to force yourself to find something that works as you're the one doing the work for no real reason. OSRS and 5E look similar but they games. 5E is basically a super hero game and OSRS matches are fantasy. If you wish to play a traditional fantasy game and your players want to play with Marvel The Avengers no quantity of house rules or different systems can really solve it. Just find things to do together with boardgames, that group or some thing, and search. Was quit my team and only start running OSRS matches for men and women that appreciated them.
What have you been playing? Neither are heroic fantasy independently, although the Black Crack and Whitehack are equally. If your players want to play with 5e, it seems appropriate to run that or possess among these DM it, or find a new play collection (and I understand the latter two are likely not real options). Is the machine that you are employing the deal breaker for them, or will be the issue more that they're searching for a more epic fantasy feel and do not care if they are using exactly the same system as Critical Role? Are they the sort of players that enjoy"building characters" (getting skills and skills by leveling up) in the video game feel? 5e appears like the thing to do if that's the case. If not, seems like being particular with rules and changing the sorts of experiences you go on may be adequate.
You might try to play something crunchy and more narratively focused. I've enjoyed what I have read of dungeon planet. There's also the Fate platform as well that I've also heard great things about storyline focus. Regrettably I don't have too much experience playing these, since it is quite hard to get my friends to try stuff besides DnD. He appreciated the attention on character customization and advancement the foci supplied. The founder, Kevin Crawford, also seems to be working on a pure fantasy version called Worlds Without Number as well with a similar focus system. His beta system can try. He has also got a few more systems that I feel are interesting, like Godbound where you play as demigods combating demigod level dangers, or Scarlet Heroes that's a system designed for low player count celebrations to make taking a couple of PCs in more workable.
Low Fantasy Gaming could try. Is for perishing to make the system more pliable imho houserule the rules. It has a Luck score and also a reroll pool to provide the players more control over the problem of an experience, but the buy RS3 gold resources deplete as they resolve challenges. Exploits provide the players a sense of service and lets them feel badass whenever they stab an eye out or decapitate someone mid-combat.
