Zynga shutting down Street Racing game, offering credit for in-game purchases

Casual giant
Zynga is
shutting down its
Street Racing game on August 2, immediately rendering void all the in-game items players bought with real money. Zynga offered no explanation in the announcement, simply suggesting that players try other Zynga games. Naturally, people whose fake worlds have crashed around them are upset, starting a petition in
Zynga's forum to stop the game from disappearing.
Zynga told
Develop that it wouldn't be offering refunds on the money spent in-game, opting instead to give credits equivalent to the cost of any purchase made in the last 90 days, plus an extra 100 units of virtual currency, all usable in other Zynga games. Which is
really going to satisfy the
people planning to stop playing Zynga games when
Street Racing goes away.
