The Game was already finanzed, so I think the Foundersprogramm is more like a Preorder/get in early.
Below I will list the packs, but pls keep in mind that I would only buy in, if you trust the Developers, because there are many things we don't know yet, and the game is in Prealpha.
Or if you love WH40k
There are several packs available in the Founderstore:
https://www.eternalcrusade.com/founder-store
The Warriorpack 40$. I would highly recommend this one, because it's not only the cheapest option the get
the full game, but has also the best value.
A Game key and 4 character slots ($40 value) with Warrior Founder program exclusives including:
40,000 RTP to Spend in the Rogue Trader (Shop)
Pre-Launch Game Access â First come, first serve!
Early Game Module Access â 60 Days after Initial Access â Third Wave
Arkhona Vanguard Title
Exclusive Founder Lounge Access in Forum
Reserve Character Name
Reserve Guild Name
The gamekey is worth 40$ and 40000 points also would normally cost 40$, so you basically get 80$ Value for 40$. 4 Charakter slots are all you need, because then you can make one charakter for every Faction. One Charakter can spawn as every Class, like for example in Battlefield 4.
The 80$ Seargentpack:
You get everything from the Warriorpack +
-15% more Points, that means a total of 92000 Points.
-Limited Edition Banner
-Limited Edition Emblem
-Early Game Module Access â 30 Days after Initial Access â Second Wave
The 120$ Captainpack:
You get everthing from the Seargentpack +
-25% Bonuspoints for a total of 150000 points.
-Early Game Module Access â Initial Access â First Wave
If you have too much money you could also buy the Heresy- or Xenospack, which cost 250$ or 450$. These are only Combipacks. Heresy is Captain + all Heresy Weapons, Xenos is Captain + a buttload of pointbundles. Maybe look into the Subscripton Model, if you could get more Points longterm.
You can also always buy more points,
If you reach enough points for the next founderlevel you also get those title and preorderboni!
You can also play
for Free as
some of the basic Ork classes, and if you want, later unlock more classes. (Free2Waaagh!) I think this might be a good Idea, if you are not sure about the game and want to test it first.
It's already confirmed that the Prices in the Ingamestore (Roguetrader) will go down soon! Atleast untill Beta starts, everything you have in your Basket in the Roguetrader, you can take out again! Your choices are in no way finale!
In general I would recommend for many to wait a bit and see how the game develops, but after I discovered that this game was in the making, I wanted to be Part of it right now

It's not only the WH40k "lore" game, but also the persistent World PvP game I always wanted, so for me personally it was a no brainer.
