Once tomorrow’s PSN update is live, PSOne classics R-Type Delta and R-Types will be removed from the service. This may be permanent, making today the last day to snag ’em. It’s unclear what is prompting the removal, most likely stemming from a license expiration. Both titles are available for $5.99. Better to have them and not care for them than to spend the rest of your life wondering “What if?”.
Or you could always buy the PS1 versions.
