Lol, not to nit-pick, but luck had nothing to do with Luke being trained. Anakin, yeah, but Luke was hidden and monitored by Obi-Wan (at Yoda's behest) specifically for the purpose he eventually served. Still, you're right about Tatooine being a bit 'out there'.
Coruscant seems quite the Jedi breeding ground in these games, I've noticed. Although I imagine that a great number of Jedi are found there, considering the population size and diversity, and not least the proximity to the Temple. It's easier to see something in your backyard than across town, if you catch my drift.
