^The Spirits Within is not Final Fantasy, it's Final Fantashit.

You could play any Final Fantasy game, they have tons of remakes, and some are easily available for emulation if you can't find them. Though pretty much every FF game starting with FF4 is different to the point some feel like completely different games.

Some, like FF10 and FF13, focus on the story, and are pretty linear. Others, like FF7, are more open-world. The combat is also radically different at times.

Now, regarding Crossovers. Wasn't there a Sonic/Megaman crossover comic once? And a Star Wars/Soul Calibur crossover too? And that's not including things that are technically non-canon, like Super Smash Bros. or FusionFall, or Fire EmblemxShin Megami Tensei.
