Cheat codes you remember

[Korovashya]

All your base are belong to us!

I think you know where it's from.

Most of these are from Rome Total War. I was devastated when they took the console out of Empire. I mean, I still beat the game, but it wasn't anywhere near as fun.

Add_money 40000
Oliphaunt
give_trait
give_ancillary

Also, from DA:
Wipe on High Dragon --> Windows+M --> Open internet explorer --> search "Dragon Age cheats" --> Reluctantly open IGN --> Edit files; enable console --> Open DA --> Click console button --> Panic --> alt+tab --> search "DA mods" --> Download game-breaking sword --> Sigh in relief.

pokemon rare candy cheat (infinite item cheat)
put your desired item in the sixth position on item list. i think its sixth. talk to the guy who shows you how to catch pokemon. fly to cinnabar island and surf along far side of island until missingno appears. apparantly the reason this is a cheat is because missingno is number 0 pokemon, hence the name missingno (missing number).

How to play Jedi Knight II, the boring way (as I later found out when I was older and decided to beat it using actual skill).

Though, running around chopping up Stormtroopers and the like was fun... for a while.
