What is inherently required for a videogame to be "good?" State what qualities you believe are necessary to make a "perfect" game if possible.

I think a good story line, good graphics, games that make you think... good strategy games.
Some good games: final fantasy games. civilization 3. ALL zelda games! fate of the dragon. dynasty warriors 3. Onimusha. GOLDEN EYE! metroid (for reg nintendo.) Castle vania games. parasite eve. clock tower. silent hill. resident evil. Shogun total war. command and conquer series. Age of Empires 2. The sims.. its so addictive! Turok (shh i liked it!!!) Wolfenstein. Thief.

Now for future reference, not ALL of those games are favorites of mine. I just know they are good games.
