Personally I'm totally okay with the soundstage not being so wide. I don't have that much experience with wiiiiide soundstage, though I do have a pair of m40x's with angled sheepskin pads which to my knowledge are supposed to sound somewhat spacious. I don't really like them, though.
They had pretty good imaging in their stock form (although horrible comfort), but replacing the pads resulted in an awkward sensation of the soundstage being overly stretched to each side while taking away from feeling of being able to pinpoint the direction of sounds. The sound signature is nice, but that sensation makes them kind of weird to me, mainly when gaming. I think I read a comment somewhere describing the X2's in a similar fashion, but I imagine something like the 7xx's or the 'spensive headphones I mentioned to give off a slightly more natural feeling of width. I can't really speak for those yet. Maybe someday I'll save up for the Erupts, as the things I've heard and read about them sounds amazing, but so far my budget just doesn't justify any more expensive headphone purchases, especially not a model that's still undergoing calibration.
I like the sensation of sounds coming mostly from believable directions, though, especially when the soundscape is rich, and you can hear lots of stuff going on at once. Payday 2 is a prime example, although in that game there's almost so much going on that it's difficult to really make strategic use of the ability to hear directions anyways. The Long Dark, The Hunter: COTW, Alien: Isolation, Prey, Black Mesa, The Witcher 3, SOMA, and, surprisingly, Planet Coaster have quite a bit going for them in terms of environmental sound, I think those games are particularly immersive with the Jubilees. Killing Floor 2 is meh, but tbh I don't find the atmosphere in that game particularly enchanting anyways. If you like horror, particularly in first person, I think the Jubilees will excel at that. The sound design in SOMA is completely nuts, you can hear a pencil rolling across a table and tell pretty much exactly where it is. Michael Bay'esque all-out action games and RTS's would probably be the ones benefitting the most from a wide soundstage, I think. RPGs, atmospheric outdoors experiences, 2d games, you should probably be good with either.
The imaging actually also works surprisingly well in old games that have nothing in the way of virtual surround simulation apart from sound playing in a radius around their source, like Morrowind and Oblivion, although the sound in those games could probably also do well with a bit more sense of width.
How well both soundstage and imaging works in general works, however, seems to depend quite a bit on the mixing of whatever you're listening to, games included, and the quality of any systems simulating how the sound works in the game, so in some games directional ques sound more natural than others, and the soundstage may appear more spacious in some titles than others. There's no problems with the soundstage coming across as narrow to me in The Division, for example. In 2d games there seems to be almost no benefit of good imaging apart from that to the soundtrack playing.
The imaging and separation of the Jubilees also works really well in music that has a very "surround'esque" feel to it. DVA's soundtracks to Botanicula and Chuchel are really fun and trippy to listen to. The separation is fun too in itself, although probably not quite unique to the Jubilees in their price range. I have no problem talking to people over Discord, while having a game paused in the background that I can hear the sounds from, while listening to music at the same time without basically any of those things drowning out each other in the least. That's what's happening while I'm typing this.
To be honest, tho, I think it's difficult to fully answer your query without having tried more headphones than I have. It's very much a personal preference thing, I guess. Again, just different flavours of headphones. Those are my 2 cents at least, though.
