Exclusive games are definitely important, if certain games weren't exclusive then there wouldn't be a reason to own more than one current gen console. If there were no exclusive games then the companies behind the consoles would then need to give much more incentive to buy their console but currently all of them are practically the same feature wise. People would simply buy the console their friends were getting or the console that has the better UI that suits them. I currently own the PS4 and XB1 but I have literally like 3 games for the XB1 due to the fact that they are exclusive titles (Halo, Rare Replay and Gears of War). If they weren't exclusive I wouldn't have even bought and XB. Same for the Nintendo consoles, while the Switch has the feature to take it anywhere in the world and continue to play as normal, it's unfortunately the only feature that is different than the other consoles. They all cost money to play online and they all give away free games every month, so really why bother buying the system other than to play the new Zelda game or the next Halo? Exclusives are currently what drive the sales of the console in my opinion
