The ps Vita is sony's next-gen portable console, But sometimes it's like they forget the system even exist. The system is in need of more non spin-off exclusives. And The last Guardian is the perfect choice,
I heard the game is being re-engineered and the ps4 does not need the game (neither does the ps3) so this leaves one choice. The Ps vita. This games is highly wanted by many playstation fans, so making this a ps vita exclusive well ensure some sells.
Well right now the biggest concern for The Last Guardian is the release date. It's concerning that back in E3 2009, they showed the trailer for the first time and they have been posting delay after delay. I do agree with the concern for the Vita though. It does need more AAA titles to keep it alive.
I don't think the Vita could handle a game like The Last Guardian, especially since it's now being "re-engineered" (see link below).
At this point, I just want to see the game released. As IGN states, it was first announced around four years ago.
