Mirai Nikki, Eden no Ori Recommendations
Like games? Like psychological plot holes? Like horror? Like action? Like romance? Then, you might like both of these manga series. Both the main protagonists begin as ordinary people but are quickly thrown into a setting they never imagined before. There are also evidence of romance and drama as the chapters drag on. Additionally, there are quite a lot of character development not only in the main characters but some of the main supporting as well.
