Some older online games have pretty good latency tolerance because they were built in an era before broadband was widely available.

Vanilla World of Warcraft, for example, has a ‘spell batching’ mechanic that helps to equalise things somewhat. You’ll need to play on a private server though because Blizz changed spell batching in Classic.

Chess, Tabletop simulator, collector card games.

So for an MMO OSRS is amazing with this. I can usually connect across the world and notice no lag. In fact I don’t know if I’ve ever had lag with it, whatever they’re doing it’s great.

I wouldn’t think that most WiFi setups in and of themselves would lead to much, if any, added latency. Wiring up your systems is always ideal in terms of reliability, but plenty of people (I’d bet most) game online via WiFi. I’d suspect that if you’re dealing with latency issues it’d be from playing on distant servers or some other bottleneck in your network.

One couple I regularly game with are on Starlink and I believe both their computers are on WiFi and lag is (generally) fine for them when playing action-survival games like 7 Days to Die, Ark, and Valheim. Their only issues are generally from when Starlink has a momentary hiccup.

Autobattlers like teamfight tactics are playable with over 200 ping.

Payday The Heist cause the worse of a connection the host has, the easier the BS onslaughts on high difficulties get lol

You can play a ton of turn based board games on boardgamearena.com

You can play real time or turn based. It works on any browser, even mobile.

Some real time strategy games might also work. I suspect Age of Empires 2 won’t be too problematic if the high latency only makes your orders take a bit longer to happen. Warcraft 3 (the original release) might also be worth checking, you can find private lobbies to use in place of Battle.Net. I suspect most Total War games might do fine, too, as even the real time battles don’t require a million clicks per second.

Old MMORPGs can also remain playable with up to ~600ms of latency, so you could give a try to WoW on private servers running older expansions, FF14 (free up to level 60, I think) or Guild Wars 2, for instance.

Wi-Fi itself is not likely to cause issues. Incorrectly set up or in a highly dense area with a lot of competing networks you may see some issues, but due to packet loss not latency. If you are in an area where it’s legitimately a problem and not just PEBCAK then there are alternatives to both Wi-Fi and running ethernet cables all over the place, like powerline networking.

But on to ping itself, unless you’re on extremely high ping it’s so rare to find a game where it’ll be an issue. Competitive reflex based games like low TTK shooters, sure, though when I use to play tournaments in an FPS I qualified just above 300ms before the actual LAN events. Americans start crying at like 80ms which is hilarious.
