I've finished my 2nd DOS2 playthrough yesterday evening on Tactician. I'm not an achievement hunter, but I've looked up achievements out of curiosity, because I felt like I was missing most, which, to me, implies I've missed heaps in the game. I've seen an achievement for arena. Now, I know you can trigger it by making a fake local arena, but it got me thinking: it would be a great promotional thing and a new life for the DOS2 Arena mode, if it was released as a standalone F2P. I never got to play vs another player, and I think it would be cool if it became possible. It would make for a great publicity stunt, I reckon.
