The Grand List of Console Role-Playing Game Cliches
Let's not mince words: you're a thief. You can walk into just about anybody's house like the door wasn't even locked. You just barge right in and start looking for stuff. Anything you can find that's not nailed down is yours to keep. You will often walk into perfect strangers' houses, lift their precious artifacts, and then chat with them like you were old neighbors as you head back out with their family heirlooms under your arm. Unfortunately, this never works in stores.
No matter what timeframe the game is set in -- past, present, or future -- the main hero and his antagonist will both use a sword for a weapon. (Therefore, you can identify your antagonist pretty easily right from the start of the game just by looking for the other guy who uses a sword.) These swords will be far more powerful than any gun and often capable of distance attacks.
And no matter how big that big-ass sword is, you won't stand out in a crowd. Nobody ever crosses the street to avoid you or seems to be especially shocked or alarmed when a heavily armed gang bursts into their house during dinner, rummages through their posessions, and demands to know if they've seen a black-caped man. People can get used to anything, apparently.
