I would like to revisit the older generation of consoles (e.g. the PS2, GCN, N64) with the games in my native language (Spanish), but the vast majority of NTSC games weren't in that language. And even to the present day some companies refuse to localise the games in Latin American Spanish or Mexican Spanish, though. That being said, I would like to play these games series in my native language:
• Yakuza / Like a Dragon series
• The older Grand Theft Auto games (e.g. IV, Chinatown Wars, Vice City Stories)
• The entire Burnout series
• Some Need for Speed games (e.g. Most Wanted 2005, Underground, Underground 2, Hot Pursuit 2010)
• Persona 3, 4 and 5
• The vast majority of the Nintendo games catalogue from ~2007 and older.
• The vast majority of the Sony games catalogue from ~2010 and older.
I grew up playing with the N64, and well, the 95% of the games from that console were in English. That helped me to improve my English from an early age. But, I noticed some games (Need for Speed series) had some entries in my language, like Carbon, ProStreet, Undercover and The Run, but the remaining games aren't in LATAM/MX Spanish, they are in Castilian Spanish, though. And some other companies don't localise the games at all (SEGA/Atlus, they started localising the games earlier this year, but slowly).
