There are other topics discussing the "best" Ratchet game, or good places to start if you want to get into the franchise more seriously. If, however, I am purely interested in playing 1 and only 1 Ratchet & Clank game, which one would give me the best overall Ratchet & Clank experience? I know virtually nothing about the franchise, but want to see what it's all about, and can't commit the time needed to playing them all. What say you bombadeers!?
Also, ignore logistics (cost, platforms, etc.) and assume I have equal access to all games.
