Got a noobie question about the EA and Rockstar story

So since Rockstar is declining EA's $2billion offer. What would it mean if EA buys all the stock to R*?

What kind of effect would that have and why should we be worrried?

A stock means part of the company. If EA buys enough stock in Take2 (the publishers of Rockstar games), they effectively own the majority of the company and anything EA says is what will happen. If EA says "hey lets merge!" then thats what will happen.

However, given the size of a company like Take2, even if they are dwarfed by EA, its unlikely to happen. It would cost EA billions and billions of dollars.
