It seems like most people have already hit on the point that branding is extremely important, so even if you change some aspects of your t-shirt design you want the overall appearance to be recognizable from year to year. Changing just one side of the shirt, or keeping the same color scheme and certain aspects but adding game-specific designs seems like it may be a good option if you do want new designs each year. 1124 re-branded as the UberBots in 2005 after our main sponsor changed, and we didn't come up with a logo until 2006, but since then our shirts have been essentially the same each year because of the branding aspect.
