Spider-Man, the Insomniac’s game, has been launched on PC. If you enjoy the adventures of Spidey, play it. The title includes some references that could indicate that Sony is working to integrate PlayStation Network accounts to specific games and offer some extras as a reward for it.
The PC port of Spider-Man includes files names as “PSNAccountLinked” and “PSNLinkingEntitlements”. Therefore, Sony does not offer connectivity with PSN accounts for their PC games, but apparently, they are working on it according to the files discovered in Spider-Man.
Moreover, it was found a file called “LevelCapExtras” that would indicate that Insomniac is doing research to give players skills points or something in that vein for linking the players accounts.
