Not being a kickstarter nor backer, EDO did not surprise me in the least as it is the stepping stone to every other potential activity in the game. Without perambulation the player can never leave the seat of their ship, SRV or SLF. Certainly the announcement and following teaser videos served to encourage me to keep playing and make me eager to get this amazing expansion. EDO launched with many issues, but, for me at least, added a new dimesion to the game that made the wait worthwhile. I'm fortunate, I play games, lots of them, and my PC is built to mainly do just that. EDO at release taxed my PC at release, now it has improved sufficiently to be extremely playable and makes less demands from my PC than a few other games I enjoy.Frontier surprised me with Odyssey to begin with, even if it was obvious in hindsight.
Will there be further paid DLC development of the game? I don't know, but the business head says it is unlikely, EDO did not realise profits enough to pay for its development - the development team needed to produce a potentially profitable expansion in the future would need to have considerably greater skill in game development than the one that produced EDO, or the management the ability to recognise when a product is so far from 'reasy to release' and to prevent another abysmal launch.
