And on a side note, it would be cool if someone out there actually made a website that had statistics of how many sequels/sports games/licensed games have been released each year since the NES days. That would be super interesting to see, I have a feeling that the ratios would be pretty close during the haydays of each era.
This would be great. I love the idea.
Here are random thoughts on SEQUELS: Unfortunately, besides being labor-intensive, we'd have a lot of problems trying to categorize certain games (i.e. is SMB 2 -- US version -- really a sequel to SMB?) .... Some games kept the name of a popular franchise, just to sell, like SMB2 (US) and Legendary Axe II (US). It's tough to categorize, because they weren't developed as sequels, but they were marketed in the U.S. that way.
Should we stick with sequels appearing on the same consoles? Or should we be cross-platform (cross-platform would be a more accurate measure of sequels, but it's much harder categorize, since there are different versions of a game, and not everything is necessarilly a "sequel"...)
While many cross-platform "simultaneous" releases, ports and conversions of the "same" game are similar, let's not forget the TONS of games that were recreated distinctly for specific platforms. Ninja Gaiden on Lynx (arcade) is very different than NG on NES (original, new game). NG had "sequels" on Lynx and NES... but how do we categorize these sequels?
For example, one of the Lynx NG "sequels" is actually a port of the third NES game. So shouldn't this be counted as merely a port of an NES game, and not really a sequel to the arcade version of NG that graced Lynx prior?
I don't know. A distinction between "sequel", "straight port", "recreation", etc.... would be helpful. Then we'd have a good picture of how often things are recycled and re-hashed. A high number of "ports" across platforms isn't a bad thing, but once those different "ports" start spawning sequels...
Then there are the clones / "reskinned" engines. JJ & Jeff totally belongs in the Adventure Island / Wonderboy I universe. It's not an official sequel, but damn, shouldn't it be counted as a sequel? Now let's think about all the contemporary games that share essentially the same engine and are "reskinned"....
BOTTOM LINE: Guts, this is an awesome idea. Developing a system for consistently categorizing games is the key. The list of games w/ a series of "sequels" is daunting, but not nearly as long as the overall libraries of games specific to each platform.
