The once rosy relationship between Rhode Island and Curt Schilling appears irrevocably damaged as the former baseball star turned entrepreneur and the state’s governor traded blame over the abrupt collapse last week of the videogame company 38 Studios LLC. The finger-pointing between Gov. Lincoln Chafee and Schilling escalated Tuesday after the Sox pitcher for the first time spoke extensively about the demise of 38 Studios, accusing the state of breaking promises to help the company remain viable just as it was closing in on a deal with an outside company to salvage its major unfinished video game.
