[quote name='CheapyD']Post your nominations for Best Game Value 2010 here. What game offered up the best bang for the buck when it launched at retail?[/QUOTE]
Assassins Creed: Brotherhood
Splinter Cell: Conviction, since it had two entirely different campaigns. They may not have been the longest, but I still thought it was a good value. Plus Ubisoft released free content every week for the first month or so, which was also nice.
$20. It was the game that never left my DS and would help me through numerous long waits and flights. I've drained full charges of my battery numerous times while playing this game. Hundreds of built-in puzzles and then plenty of continuing free DLC support from Nintendo and other fans.
