Gamerbytes has compiled a list of several Xbox Live Arcade games and their performance in the first half of 2010 based on data derived from leaderboards.
First, there are the top performers: Trials HD apparently had the biggest user base, jumping from 600,000 players to over a million during the first half of 2010 (not counting its DLC, which had almost 300,000 players over that period). But how about games that launched this year? Well, Perfect Dark enlisted 265,000, and Toy Soldiers and its DLC managed to recruit a combined 346,000 players. Risk: Factions and Snoopy Flying Ace have yet to reach 100,000.
Other games didn't fare so well, with several failing to capture the attention of even 1,000 users -- Voodoo Dice, Ben 10 and Fret Nice were near or below that mark -- and of the 24 new games that Gamerbytes catalogued, only 13 managed to reach 10,000 players.
Seeing how deals and promotions affected the growth of user bases on older titles is particularly interesting in the case of Zombie Apocalypse and TMNT: ReShelled, both of which came darn close to doubling their respective audiences when discounts were applied.
