I think there’s better patterns RPGs can use for them.
A lot of games now just put them wandering the world, and touching/attacking them prompts combat. Then, the game needs to invent various motivations for you to actually want to attack the enemy.
In a lot of games, they’re just genuinely in the way through tight corridors to a destination. A better approach can be to associate some kind of minor quest reward to directly pursuing the enemies.
But, then you get the problem that a lot of RPGs just have no interesting decisions to make in combat. And, participating in combat can lead to a slow wearing down of the party’s mana points, or the game’s equivalent. In many games, you only want to use the basic cure spell and auto-attack because you’ll survive fewer fights without mana rationing. It becomes counter-intuitive and less fun.
Some games resolve this well. Cosmic Star Heroine for instance, a short indie JRPG, heals you after every fight, and each combat is uniquely scripted in for pacing much like Chrono Triggwr.
Ideally, Sony would handle the legal hurdles needed to allow PSN in multiple countries. But I imagine, as the publishers have invested tons of money into producing those singleplayer games, part of what they want in return is investment into the “PlayStation ecosystem”. Much like how Microsoft doesn’t care if people play their games on an Xbox, they just want an account.
Basically, I don’t think Sony is really in the business of putting down huge financial risks just to get the $60 entry tag of the rare singleplayer game they put out. Those games are meant to get you buying other Sony content as well.
