I've got to say, I only played the game for the first time yesterday. I immediately got my brother to download it because good co-op PvE is hard to come by these days. Super sad to hear I came just a few days after I could have gotten a lot of free content.

After playing the two available missions, my brother and I are basically done. We've got a lot appreciation for the world building and art of the game, and we both appreciate that their *is* a free-to-play model, but the grind is too steep. So NaotaKenichi's got real concerns, but maybe Mercury Steam doesn't mind?

It would be neat if players who purchased the expansions could freely invite anyone without those tickets. That would motivate me to either buy the game or encourage my brother to do so. On top of the license to host their associated campaigns, some other reward could be attached to the purchase to incentivise buying it. Like a skin or whatever?
