To me, personally, the Founders pack was worth every penny.
I liked Warframe a lot despite it being a game type that I do not usually like. Fast-phased action shooters were so low on the list; and add space ninja to that and in any normal scenario it would just have been a "nah, pass." But somehow I got stuck anyways, and I've happily spent quite a bit of money in it.
When Soulframe was announced, I knew I wanted to support DE from as early on as I possibly could; and I would have grabbed the Founders pack even if it offered nothing but arcs in return.
Now, unpacking the Founder's pack:
- I think it is perfectly reasonable, and even expected, that the pacts and the weapons should be obtainable by non-founders.
- I am slightly disappointed at the other cosmetics being available (armor + sparrows) at a later date. I think that they founder armor is.... Okay to allow people to achieve ingame... But when it comes to smaller things like the Guide (sparrow) skins, then I wish they'd kept it unique, though it is not a make-or-break point for me.
One of the reason I bought quite a few Prime Access packs for Warframe was for their limited edition value. If SF is not going to walk the same path, then I guess my wallet is going to thank me in the long run. 😅
