Guys, let's get reasonable here. We live in bone-breaking capitalism (a dog-eat-dog world, the big fish eat the small one, the survival of the fittest etc.) and the video gaming industry is just like any other kind of industry, the game designing and publishing companies are just like any other companies; they put money and profit above everything else! The system always worked like this and it doesn't show any signs it tries to change at all.
Rivalties and sue issues have a long, big history in videogame industry. Each company try to buy or sue the other one and vice versa! Even the reviews of all these various videogames that has passed are about money; is the company rich enough to bribe the reviewers in order for their game to get a pure 10/10 and therefore advertising it through the gamers, or it is a small garage company which never had a chance in the first place and being axed mercilessly by the reviewers?
There is no love between companies, just profit!
