Square Enix has one of the most impressive back catalogs in video game history, yet it loathes to share all of its titles in every region, as Chrono Cross is still not available to purchase in Europe, even though it was released over twenty years ago.
There was a time when Japanese video game developers/publishers believed that RPGs didn't sell well in the west. This led to many JRPGs never receiving English localizations during the 8-bit and 16-bit eras. It was only the biggest games (like Chrono Trigger and Final Fantasy VI) that saw a release in North America. Things were even worse in Europe, as many JRPGs were never released in places like the UK, even though English localizations were already completed.
The 32-bit era brought Final Fantasy VII to the original PlayStation and a JRPG boom began, yet Square Enix (then called Squaresoft) was reticent to release all of its titles in Europe. Games like Final Fantasy Tactics and Parasite Eve were never released in the UK and gamers in the region had to resort to piracy in order to play them.
One game that was absent in Europe was Chrono Cross, though there was at least some explanation as to why it wasn't brought over. Chrono Cross was the sequel to Chrono Trigger, which was released in North America, but not in Europe. Chrono Cross is a distant sequel to Chrono Trigger and it's possible to enjoy the game without experiencing the story of its predecessor, so even this was a weak excuse not to bring it over. Chrono Cross was later added to the PlayStation Network in North America, which meant that it could be played on PlayStation 3, PlayStation Portable, and PlayStation Vita systems, yet it still wasn't added to the European PSN service. It's possible for people in Europe to create international accounts and buy Chrono Cross on the North American store, but this comes with its own share of hassles, especially when it comes to adding cash to their account.
Chrono Trigger eventually received a European release when it was brought to the Nintendo DS in 2008. It would later receive ports for mobile phones and was brought to Steam in 2018, so it's easier than ever to play the game. Despite this, Chrono Cross is still not available on the EU PSN store.
Square Enix has discussed the possibility of creating its own digital storefront for its back catalog, in the same vein as Steam. If this does come to pass, then games like Chrono Cross would be a natural fit, especially as it's only available on older platforms or through illegal means. The game would also benefit from the remastered treatment that the PlayStation Final Fantasy games have received on modern systems.
Chrono Cross might have drawn the ire of Chrono Trigger fans, due to its treatment of the beloved cast of the original game, but it's still an excellent title in its own right and more people should have the chance to play it.
