Would like to start some new series but I don't want the games to be long. Final Fantasy 13 was very tiresome and boring

Hyperdimension Neptunia Re:Birth. The second game is notably longer, so up to you.

Cold Steel IV just recently came to PC so I'd recommend the Legend of Heroes of series.

Atelier games are pretty short and you can get all the ps2 era ones on the Nintendo eshop
