The "Alpha" label.
DISCLAIMER - I realize it's just a title, and that we have been graced with updated content for nearly 8 years for a relatively small initial purchase price, and I fully appreciate that. Love me some 7d2d... But for some reason, even with all that said, it still bugs me to no end to hear the word alpha associated with a project that's been in development for so long
Keep 'em coming though, it's been a fun ride. I've never had any other game give me this much entertainment for this small of an investment. I'll buy the next game(s) the day they drop just because I want to support this dev team.
