I blame the fact that most of the kitbashes, art and other shows of variation are imperial sided in the base material. You had alternate armor for marines and handfuls of IG regiments decades ago, but xeno stuff has almost always been shown as stock. The main eldar variation (after their rework from the chainmail and metal hair of RT), was a single corsair kill team. Tau never got even that.

I think you haven't been looking hard enough then anon.
Or GW's lawyers move quicker on xenos/Eldar when it comes to throwing out DMCAs or whatever copyright mechanism there is to take them down than Imperial Guard stuff.
But space marines by sheer volume make them appear more prevalent but GW will get them eventually as much as I wish that wasn't the case.

Marines sell well for a reason (the space knight is clearly a popular look) and between that and the Guard you can cover an awful lot of SF aesthetics.
Eldar and Tau especially have a more specific look to them, though Tau obviously slot into a cleaner, more streamlined universe style. I wouldn't be surprised to find a lot of not-Nids out there either, bugs are bugs.
I find there are a few slaaneshi daemons, but frankly that's usually a toss up as to whether the designer is aiming at warhammer or just wants monstergirls and calling them 'lust demons' (nudge nudge, wink wink) gets a few more hits. They generally have the flaw of "because I can do delicate fiddly detail, I MUST"; standing on delicate deer hooves is nice art, but not so great when you're trying to glue a 28/30mm model to a base.

There's also like 20+ reasonably popular space marine chapters that people want custom bits for but will never get official support for an upgrade sprue like the 1st founding chapters get. So that's eating up a lot of space but it's the kind of space that I understand has a market. People want their space shark upgrades and what have you so they look as cool as the guy running space wolves or blood angels.

What do the Xenos factions have that's really compatible? Wacky Ork themes? We've had sites for that for ages.

>>97836748 is correct OP, there are plenty of xenos 1:1s out there you just have to struggle to find them because they need to use even more retarded naming schemes or were found and nuked by GeW Legal so only exist in trannygram groups.
