Besides optimization to a platform, why care about exclusivity?

[Dallinor]

I paid a premium for my console because of the exclusive titles it offered and the future exclusive titles in the pipeline. It was the single most important factor in my console choice in the beginning.

Secondly, if a rival console was offering superior exclusive content after a few years, I would probably re-evaluate my decision at that point in time and perhaps trade-in and switch consoles to enjoy the better exclusive support.

It's hugely important to me, exclusive games have offered me the most entertainment in gaming this generation.

To answer your question though, that's extremely simple- Some people are far too attached to their console of choice.
