I personally think re-playing the game would turn out bad in the end.. I'm sure 90% of 1,000 teams would end up haveing a flip out right away and be completely stunned, but after a few days it would really fall into the favor of the good teams from 2005..
I know my team would probably keep the same design, maybe altering how we held the tetras so we could have a faster robot, and work on loading in the auto loader. Not to mention all the teams that copy Team 71's design
..
Any rookie that entered in 2006 with a replay of the 2005 game would probably not stand a chance and be discouraged for 2007 at how badly the vetran robots at every regional would beat them (not to say rookies won't have potential.. just playing a game in back to back years would kill anyshot for rookie success).. It's not fair to ask rookie teams going to UTC to possibly face a lineup of robots like HYPER, GaelForce, RAGE, Sie-h20-bots, MAX, GUS, Cybernights, BUZZ, Gael Hawks, Rocketeers, etc.. (very possible that lineup could happen since all those teams were there either in 2004 and/or 2005)..
