I like what CIG already has shown us (and given us to play around in), but I am still wondering about a lot of gameplay elements. The thing I am worried about the most is about all the "jobs" that the universe is supposed to give to players: running fuel, running passengers, offering tow-services, offering Medical and Repair services, picking up ejected players and such. Other MMO's seem to move away from "chores" in their development, or during their lifetime if they had them to start with.
If we look at an ejected player floating in space having the option of being picked up by a player with the appropriate tools/ship, this seems like a worse variant of having to ask around for players who could "bind" you in Everquest. Even if the proces of connecting the "victim" and the "savior" with eachother is smooth and painless (through some sort of communication) I feel this is never going to be really fun for either player.
A lot of the (transport) "services" (bring me fuel, a new ship, repairs, healing) also seem to have other options of obtaining them, especially when you think of organizations(Guilds) who tend to be self-sustaining in MMO's when it comes to services (classes). So still hard to see how being one of 3000 lone ranger "tow-truck" companies is going to be feasible(or fun), even if 90% of our jobs are from NPCs.
Offering other options in exchange for UEC will endanger these jobs even more(I am assuming you can choose to respawn even when you are not dead, for a hefty cost).
Also wondering about progression ( no paper doll with stats, instead you buy better ships and better upgrades and accumulate money), especially since this progression is dependant on your jobs and the Economy. Not saying there is no other fun to be had in this game, other then performing jobs with your ships! But let us not underestimate the deep-felt wish from most gamers to experience some solid progression in their game.
I guess I would like to read a little more about how fleshed out PvE (missions) will be, that is not reliant on content generated by players.
