I don't like this either. I love my PSP and games are either being made for the PSP but staying in Japan due to "the amount of piracy in the west.(quoted from Sega when asked about Valkyria Chronicles 3)" or it just doesn't get many games developed for it because of the same reason.
After the amount of times Dissidia Duodecim was pirated and the poor sales it's received, Square-Enix even stated they're unsure of localizing Final Fantasy Type-0 for the west because of the piracy. This makes me sad

FF4 Collection as others have said is amazing. The After Years kind of sucks, but it's the overall best version of FF4.
Phantasy Star didn't get worse after the Genesis games. Phantasy Star Online is where the series really reached its peak, even if it is a completely different game. PSO, PSO Episode 2, PSO Episode 4 were all just more of the exact same type of gameplay and it was fun.
Then Phantasy Star Universe came out. It's not terrible, but it's a watered down version of PSO. Forces were once my favorite class, but in PSU and PSP they're just not really fun to play as, so I stick to the Hunter class and sometimes, although rarely, the Ranger. PSP expanded on PSU, and PSP2 made it much better. PSP2 even adds areas like Forest, Cave, Ruins, and Mine from PSO. Even though the games aren't as good as PSO, they're still good games. I'd recommend skipping PSP and getting PSP2. The reason to play these games are the network portions, not for the story mode.
