The "series" is more of a cosmetic thing, a way to organise the sale of multiple CPUs and making it easier to view without having multiple sale tabs on.

Dev You need to work more on this game, literally so much potential you have no idea. It's such a fun cool game.

Two things: First, i agree with haxorfan. Second, hardware series-es could actually help a ton. The reviewers could make comparisons to previous hardware in the series to make more constructive feedback. “All in all, it’s a pretty mediocre CPU compared to the last one.” Then, the player could see what was different and improve on the next one. All in all, it would be a pretty useful feature. (see what i did there?)
