Vanduul swarm co-op? Nice. Any idea how many human players that's limited to?
Its 2-4 player co-op. Perfect for getting a few org-mates in and having some fun together.
Cant see a reason why it wouldnt be as good a time as any to pledge for a ship package
If you've got limited funds and there's a full game you're interested in, then you'll most likely get more from the FG now than you would in SC. But otherwise, it makes little difference buying it now or in 6mo, you'll just get access to it earlier.
You could just as easily buy the 300i package, and later on buy the 300-325 upgrade when that ship is playable, currently only 3 ships are in (basic Aurora, 300 & Hornet) with the variants coming eventually so you'd be able to look in the 325, but you'd only be able to fly the 300i for the time being.
As for PvP, Arena Commander is a small sample of that, feels more like Quake Arena in its size, whereas in the PU it'd probably more strategic and require more to do meaningful damage & blow a ship up. As mentioned, you'll need to do the PvP in areas which are free to do so, or be targeting pirates & bounties, rather than attacking UEE citizens without justification in a UEE policed zone.
Deeper & darker areas of space it'll be kinda lawless, but it'll be worth remembering you wont be the only one out there, there will be groups looking for a fight, so going in with 1 325 will be tricky, you could be easy prey. Best thing to do would be find an Org with similar ideology, fly with a few people and work as a team. You can probably get away with a few roles solo, but PvP could be tricky if there is a lot of teamwork, you'll certainly encounter some large squads, but maybe also a lot of loners too. Hard to tell.
