If you're up for trying something a little bit different, you might want to go and check out the latest Humble 'Neptunia' Bundle. The Neptunia series is not exactly easy to explain, but it's essentially a collection of cutesy JRPGs that serve as satire of the gaming industry, going as far as to make the main characters personifications of various consoles and platforms.
The Humble 'Neptunia' Bundle will be around for another five days, and if you're curious about the series, allow me to share with you the list of games and the pricing tier they appear in. Have a gander:
Pay $1 (about €0.88) or more to unlock:
• Amnesia: Memories
• Hyperdimension Neptunia Re;Birth1 Deluxe Edition Bundle
• Hyperdimension Neptunia Re;Birth1 Colosseum + Characters DLC
• Hyperdimension Neptunia Re;Birth2 Deluxe Edition Bundle
Pay more than the average of $6.93 (about €6.10) to also unlock:
• Hyperdimension Neptunia Re;Birth3 Deluxe Edition Bundle
• Hyperdimension Neptunia U: Action Unleashed
• Cyberdimension Neptunia: 4 Goddesses Online - Deluxe Pack
Pay $12 (about €10.56) or more to also unlock:
• Megadimension Neptunia VII Digital Deluxe Edition
• Megadimension Neptunia VIIR - Deluxe Bundle
If you're wondering which game to start with, I'm afraid I can offer you very little in terms of help as the Neptunia series is just not my cup of tea. That said, pretty much all of them have ridiculously good reviews on Steam, so if you're simply looking to test the waters and see if you can get into the series, I would say grab the the first tier and check out one of them. Who knows, you might just find something you like.
Have fun, and I'll leave you with one of the trailers, just for good measure.
