Just wanted to let people know Tesseraction Games are honorable folks.
While Enigma:Rising Tide was in early beta, in order to generate some cash flow, they made an offer that for a modest donation you could received the the beta on CD. Then when the game was finished they'd send you a copy of the commerical release for no additional charge. They were true to their word and sent me the full commerical game, shipping included, full original hardcopy docs too.
It may take time but I'm sure they'll do everything they can to keep their promises.
