Focusing on marines was a mistake imo.
They make up less than 1% of the Imperium's population, but receive most of the attention and marketing.
The Imperial Guard should have been the focus. You know, actual humans instead of boring ubermensch with daddy issues.
Fantasy, for it's flaws, did try to spread the love around a little with factions instead of muh asstardes.
Fortunately, I don't see a single Space Marine in the player's party so far, so that's promising I guess. From what I read in this thread the only marine so far has been a chaos marine who was basically a mini-boss, and that's how they should be; extremely rare, but very dangerous encounters. Instead of 15 point per model cannon fodder that deploys on mass on a planet that's just begging to get wiped out with a well placed nuke.
SM are not even 0.1% , there is only like few million of them in the million worlds spanning Imeprium.
Yeah, it's something ridiculously small, and yet they show up everywhere. It's kind of silly, especially when they are supposed to operate in small, rapid strike squads yet are often portrayed in engaging in mass battles with thousands of marines fighting at once.
Because that can't possibly go wrong. /s
The setting seems a lot less grimdark and dangerous when a massive army of marines with apparently unlimited recruits and supplies can just teleport out of nowhere and beat an enemy while receiving no significant casualties, which would otherwise impair such repeated mass deployments.
Actually, their low numbers don't make sense either:
Having a huge capital ship ferry a dozen space marines (or even a company) feels like a huge waste of resources. They need to have a Matt Ward level of plot armor to achieve anything with such small numbers.
The fact that the Ultramarine chapter is supposed to control a vast amount of space (500 heavily populated worlds), with the total number of Space Marines equivalent to a single regiment of today makes them glorified administrators donning a fancy armor in a few occasions.
You would probably end up with less than 1 Space Marine for 1 Billion inhabitant or something like that (like 1-3 millions total marines for the Imperium, which spans millions of inhabited planets).
As a comparison, that's quite a few orders of magnitude less than your usual commando force, which are not even supposed to spearhead heavy assault (because Space Marines or not, drop podding on a planet should end up with a high casulaty count), or even regarding 40K numbers, that would be 10 Space Marines for 1 titan or so.
So Space Marines need to have much higher number, or be considered militarily irrelevant, or they need to have much higher numbers.
Actually, they make more sense as RPG protagonists than a useful military force.
