Not surprising there is a big crossover between SC and ED players, although i would dare to suggest that ED players are a bit more realistic about what SC might actually be than others.
On the other hand, i have seen the odd (ex)-ED player proclaim SC is going to be the game that they thought ED was going to be.
One wonders if such people will ever learn. I mean, CR aside, CIG aside, put everything else aside, but will they learn the game that exists in their head will not, and can never not, exist.
Or perhaps some previous ED players like me (actually 879h only on Steam, +Oculus) which are now dedicated to SC. For me its like b/w TV against colour TV.
