Whilst its never great to hear of a game's demise after such a short time, I really didn't think PS+ was for that. Obviously its a 'blackmail' charge to access all your games content and sweetened with the promise of free games and store discount.

If a game didn't sell well enough or being played often enough to warrant taking up Server 'space' then why keep them alive 'just in case'.

Of course from a gaming stand-point - especially if you were one of the few to have a copy or considering getting it at least, it is very disappointing news but Sony could have 'limited' servers/bandwidth and having this dedicated to game(s) no-one is playing (online at least) could be seen as a waste of resources. According to sales, just over a quarter of a million copies were sold globally with just over 100k of those in Japan (more than a third) and less than 5000 copies sold in the UK.

I don't know what investment Sony put into the development and marketing of the game, let alone the cost of maintaining and running the server for a year, but 260k sale may not of been 'profitable' or 'popular' enough to warrant maintaining servers.

Personally I can't comment on what the online functionality of this was. I don't know how much of a 'loss' online functionality is and whether or not, certain aspects - like costumes for example could be 'unlocked' permanently without the need for 'in-game' online based currency.

For fans of these games that have their 'online' component terminated after such a brief time, its obviously disappointing but Sony are a business and its a 'numbers' game. If not enough people are 'regularly' (if at all) playing these games to warrant keeping their 'servers' active, then Sony have to make a decision as to whether or not its worth keeping those servers active 'just in case' a few people want to play it or would be better to utilise those resources elsewhere. It may even be a case of Sony cutting there losses if the game wasn't profitable rather than ploughing money into running and maintaining servers and increasing those losses for the 'few' that bought the game.
