If you're taking about the documentary "Senna", then yeah, that's probably my all-time favorite documentary on any subject.
Senna's name has indeed not appeared in any games I've seen up until now. There will be some Senna content released for Gran Turismo 6 that apparently lets you follow his career path. That's why I said what I said in the review about Yamauchi. He worked with Instituto Aryton Senna and with Ayrton's sister Viviane to put that Senna content into GT6 as a tribute because of how much he admired and respected him. In Brazil they are going to release a special Senna GT6/PS3 bundle. I'm jealous, as I'd buy one in a heartbeat.
Thanks for your positive comments!
