former glory? Sega can't afford to challenge the system wars again. That reputation was lost when Saturn and especially Dreamcast called it quits. They are best as a 3rd party developer and the different systems benefit from it. If Sega still was in the console wars, we wouldn't see PSU on any system except their own.
besides if they own those games why not make money off of them in a collection? consumers benefit too since there are people who never played masterpieces like PSIV, etc. etc.
ya people hack and emulate but they are an insignificant % compared to the consumer market as a whole.
so with these collections Sega gets more money on the side to help stay afloat while retro fans get to play those games fair and square.
the same with Capcom I'm happy they released collections, that allowed me to play games I didnt have a chance at playing, and stuff like that. besides some of them were arcade exclusive and playign them on a PS2 is more convenient than owning a cabinet of it.
