I'm not sure what to do with Demon's Souls. It launched in Feb in Japan selling 38k units FW. Then it launched in USA in October selling 53k FW. And it launched in June the next year in Europe selling 30k units. All together, that's around 120k.
But by the time it launched in USA and especially in Europe, it certainly wasn't a new Ip anymore. The game had already gained several months of hype much before it's release. It didn't face the circumstances of a true new IP. Therefore, I'm not going to give it the full 120k, since it wouldn't have sold that much if it launched worldwide at the same time. Instead, I'll give it the 90k
