investments of gamers will/can balance each others.
its like saying “you buying MW2 will unbalance my BF2 gaming experience”.
keeping in mind, that Brink have little different gaming concept, than other online shooters, including [other]team/gameplay-based, ones, i see no problem here.
because Brink is already closer to MMO RPG, than others.
p.s.
concerns about impact on gameplay or other things are important, of course.
but i keep faith that SD team keep things in reasonable borders.
just croff fingers before Brink release/sales.
(I hope they didnt lie there tho…)
