Call of Cthulhu.

Bonus answer: Star Wars D6, our main game back in the day and a lot of great memories.

Mage: the Ascension. It's the only system I've ever played where I really felt like I knew MAGIC, rather than just a handful of pre-scripted tricks.

Lancer ! I did one short scenario (6 sessions IIRC) and the system and combat were a blast ! The story a little bit less, it was a homemade one for the GM. But apparently the published ones are quite good.

Oh God, Palladium. That was... A way to do things.

I fucking love G.U.R.P.S. Is it ground breaking? No. Is it fun to smash 6 different flavors together, hash out what survives, and run a short adventure or a few one-shots? Hell yeah! It's not often I run into anyone who has a fondness for the system. Hell, I get kinda excited if someones even heard of it, even if they didn't have a great experience.

Also rather enjoyed Ironclaw. I see it written off as "That Furry TT", but I had a good time with it. Would happily play more.

Scion (White Wolf). Maybe Eclipse Phase. Mutants and Masterminds.

Warhammer RPG, Earthdawn 3rd ed or Hero System is my owned top games that see too little game time.

Mutant Undergångens Arvtagare is also sorely missed on the table

Traveller seems like it would be fun with the right group

For years, all our group played was Palladium (Rifts, FRPG, and Heroes Unlimited), but I don’t think I’d ever go back to the system given other options. Combat took forever (possibly bc the GM’s threw ungodly amounts of enemies at us and refused to have anyone retreat, ever) and it felt like it just generally took forever to do anything. Also, there’s not really many adventure modules in any of the books (apart from Sourcebook 1? Just random ideas for things, but nothing to tie it together). We’ve since gone to a few other systems, but I still like to run one-shots and try out new systems whenever I can. I’ve had Year Zero in my sights for awhile and I’m prepping to run Mutant Year Zero, hoping it goes well.

Blades in the Dark and Lancer for the haven't played at all yet answer. I think both sound really cool!

One system I'd love to play more of is the D6 system that the old West End Games Star Wars used. I know they made a generic version and I always liked those mechanics. It was super fun.

I would love to do more Thirsty Sword Lesbians

F.A.T.A.L.

World of darkness (Vampire: the masquerade/Werewolf: the apocalypse). I've never played it, but a friend of mine was really enthusiastic about it and from what she told me it's really fun.

My first RPG was called "Het Oog des Meesters", translated from the original German "Die Schwarze Auge". It was probably pretty bad compared to AD&D but I loved it as a kid. In the one hand I'd love to play it again. On the other hand, playing might ruin my memory of the game. Like rewatching a bad cartoon from your childhood.

Numenera, far future setting for Cypher System. I'm the forever DM and I haven't been a player since I played the Skein of the Blackbone Bride oneshot at GenghisCon that got me into it at least 5 years ago.

Genius: the Transgression. A world of darkness fan game. I started running it in the hope I'd be able to play in a game some day. No luck. My favourite game, and I've never played in it.

Man, I wanna play Lancer so bad!

I would love to play a retro clone like Old-School Essentials, Labyrinth Lord and Swords & Wizardry. I wanted to try the old school DnD mega dungeon system.

For non-Dnd system I would like to Apocalypse World system like Monster of the Week. I downloaded a new system called Coyote and Crow that seems very interesting. It is set in a North America that was never colonized with some cool magic elements. The setting looks dope but I have no idea about the mechanics. I didn't get that far in my reading of the rules yet

Dragonbane. Got my box set, have Foundry all set up. Just need a group that wants to play.

Unknown armies 3rd edition. Did the kickstarter however long ago that was but haven't had a group in that long to try it out with.

Dresden files rpg!! I'd settle for any fate system or dresden based game tbh

Right now I'm playing Lancer and I really wish I had another campaign to try a different build/corpo. Not that I am unhappy with my choices or anything, but the more I build into what I want, the more I look at other mechs going "Hmmm...kinda want to try that too"

For something that's not as ridiculous, I really want to play some goddamn Masks. I've been thinking of running it, after the book gets a proper publishing in my country, but I also really want to play.

I almost always want to play some Masks, but still.

Rifts, although it could use an optimization pass or two on the rule set.

I really want to try OG Rifts one day

I really want to give masks a shot sometimes

Everything on my shelf. Cyborg, Forbidden Lands, Spire etc.

I got to have an intro session but then never play deadlands. I need my weird West fix!

Dune and Symbaroum

@HipsterTenZero Aftermath! Because I've always been weird. Also, Space Opera.

@HipsterTenZero at this point, anything. Savage Worlds has been my jam, though.
