it's flooded with arcade ports.
Yes but not the very specific arcade ports from a very specific arcade board that he wanted
I could see making a video about Sega neglecting the Model 3 on the Dreamcast if that in fact happened. Even if the DC was flooded with arcade ports generally, if Sega for some reason really seemed to ignore their Model 3 games, that would be a worthwhile video. Was the Dreamcast not powerful enough? Did Sega's arcade and home divisions have some kind of beef with each other? Was Sega just trying to move on to NAOMI and kill the Model 3? I'd be curious to know!
I mean as a guy who makes YouTube videos myself, I have to be careful with my critiques of other videos. I don't really have a problem with vanity projects. If a guy's into arcade racing games, then more power to him if he wants to make a video asking why there weren't more arcade racing games on the Dreamcast! (Though tbh, there were a lot. But hey, if someone wants more, I mean the mind can't control what the heart wants.)
I just think he's made up a premise that doesn't hold water for asking that question. The answer to "Dreamcast and the Model 3 - wtf went wrong?" is "nothing." Or, if you want to take a global view, the answer is "the Dreamcast was discontinued."
I skipped around a bit and then went to the end, and his conclusion is that the M3 games that did exist had issues, and Sega wanted to compete with Sony and ignore their arcade roots. And that just doesn't make sense when at least half a dozen M3 games were ported, at least four or five of them were really good, more had been rumored and even announced, and the system was cancelled after just 2 years. 100% of the reason for the games he wanted not making it onto the Dreamcast was that it had a really short lifespan, and that's it. Just imagine if the system sold 100 million units and lasted for 6 or 7 years - Sega'd be mining their back catalog for every stupid game they ever came up with, releasing tons of compilations and other budgetware to make a quick buck and fill in gaps in their release schedule wherever they could. But the Dreamcast just never had the numbers to make that either necessary or financially viable.
Tangent alert: I went to a Sega party in the 2nd year of the Dreamcast that ends up being my counterpoint to a lot of stuff like this. At that party, Sega had about 150 custom arcade machines set up with Dreamcasts running all their upcoming games. (I would love to know what happened to these, because they made marquees and everything.) That sure doesn't sound like a company ignoring their arcade roots...
