Assuming Beyond the Wall counts as D&D, because of its "B/X-ish" rules, that's 9 sessions of roughly 2-3 hours so far this year. So probably 20-25 hours in total.
A weekly, 3 hour session 5E 2024 game easily takes me over 60, even though we miss an occasional session here and there. I've also played some OSE online and in person on top of that, and a bit of Shadowdark and The Nightmares Underneath.
About 20 sessions of my Monday game (2 hrs each), 8 sessions of my weekend game (4 hrs each), and about 15 sessions of my Friday game (3 hrs) would put me decently over 100.
