It's unlikely, because the game is going to be a bigger success than Scarlet Blade from what I know.
If it's a bigger success, then obviously there's more people to buy the founders packs. Also, Scarlet Blade is a big success itself.
I agree with Yulino to say, all games are different. Also, who cares about Non-AGE games considering the fact that we're not supposed to be talking about them like that here, and secondly most companies outside of AGE suck in my opinion anyways... Now, let's not get off topic.
All games are different and I'm sure the devs wouldn't mind making one-time-only options, since both Sirius and AGE would benefit/profit off of them. And if Sirius's team is larger than those from a few other companies stated, then the more people to work on it. To get some RL items for a game that's not openly sold in stores and online is pretty cool. (Sold from the company itself too, not some fan-made stuff).
I'd love to get something like a T-Shirt, Mug, Poster, and possibly a plushie! c:
As for in-game, I'd want a one-time mount, pet, and some starter items. But the founders forum tag is really nice to have for the more active forumers such and Blue, Yulino, and maybe others who posted. I'd also want it for myself. Iyeru, if you're so against the idea though, you've made your point and you don't have to continue, my friend.
