is it possible to play gotm without those graphic packs ... they are really annoyng ...

The gamepacks are less annoying than the error messages that you will get if you elect to bypass the fundamentals that setup the game and allow it to play.

Seriously though, anyone can play a randomly generated game with a chosen civ. The challenge is for tha gmae to stay true to the central strategic principlas of game play and still provide you with a unique and memorable game experience.
