did you check out the games that Aya-shan posted ?
damn i can't wait to get my hands on "萌え萌え大戦争☆げんだいば~ん プレミアムエディション"
espacially as i were reading who is responsible for the Music ^^
rarely play Key games XP
but i know what you mean
i never use walkthroughs so its really frustrating sometimes
thats why i prefer Games with other Genres like strategy or RPG (like tears to Tiara and so)
