How this will be received depends greatly on a few key details which are absent right now.

First off, we're not sure how much one of these "titles" will cost. It's just as likely that they would, individually, be less than the default retail price of $50 as it is that they would be full-priced. Additionally, we don't know how they will be released, or exactly how each release will be different. I would think, using basic logic, that the Battle.Net/multiplayer experiences across all the titles would be just about the same, if not exactly so.

Another mystery has to do with when each will be released. Will they be released all at once? Will they be released in succession or with a few months, or perhaps a year, in between? If they are released at different times, will each contain updates and upgrades like Brood War and Frozen Throne did before them?

Honestly, I'm not sure if this is a good or bad thing, and I won't be sure until most of these questions are answered. I will say this, though: Paying more is never ideal, and no matter what we're paying for, it won't go past without much complaint.
