These uploads have better video quality compared to the smash bros ads I found, but they also have a slightly obnoxious watermark sidebar and intro that I know weren't on other uploads I saw.
Anyways, there was a running ting in SEGA dreamcast ads for a bit where they just did original animations that were basically a crossover of all the games they had on the console at the time to some extent using the actual in-game models. There's kind of a weird coherence to it all despite the disparaging styles going on, and that kind of fit given how varied the dreamcast's library was. Most games got ported elsewhere after it died, and some of those games were just mildly graphically improved ports of stuff on other systems, but I don't think companies would be willing to let something like this happen nowadays unless they legally own every single aspect of it or it's a brand deal in some third party thing like fortnite that doesn't show the different things intermingling despite them being intermingled in the game itself. can't have "potential brand damage" I guess.
I somehow forgot just how SEGA advertised the dreamcast had online gaming. Then again I also somehow never noticed how the fuck it was supposed to work as a kid and probably just assumed it was only on "newer dreamcasts" or whatever.
There's a voiceover here but it has purpose
