Oh, and being more in-topic, Superdimension Neptunia x Sega Hard Girls gets released in EU PSN Store in 21th October. (But chances are you guys may have known this already.)
The Re;Birth set are remakes of the first 3 games, and as such are based on an improved version of the 3rd game's engine. I've loved the series, and Re;Birth1 is only really grindy at one or two particular parts. Other than that the only grinding that comes to mind is optional grinding for materials to makes things/get achievements. Definitely worth checking out though they'll very likely go on sale in the holiday season, they always do (Usually 50% off for the Re;Birth games) and are absolutely worth the price.
On the other hand, if you're looking for something a little more stand-alone and not part of a (now rather big) series, Fairy Fencer F might be a bit more up your alley. Same creators, similar overall style of gameplay but with its own twists.
Following on from my previous post, the Blanc + Neptune spinoff came to Steam little over 2 weeks ago, VII came to PC a few months back, and the game the topic is about has PC listed on its ESRB page, which has been the giveaway for previous titles that it's coming to PC.
