Welcome to the club. \o/
You lucky bastard, be sure to be devoted to her.
...nevermind.
Nothing because we're besides being perverts also damn lazy.
There's only one way to find this out...
Let's make a new visual novel with the title 'Sandwiched by Zaig my wife and her sister Majin.'
I'm sorry though but I've to decline. I already have my personal sandwich (dan and desi-chan).
Dammit Zaig, that's fate! Let's start going out! Also, the only thing I really use my handy for is its alarm-clock function. It's like 20% alarm-clock, 10% SMS, 2% phoning and 68% collecting dust. So yeah, I love my phone.
Hahahaha, like I would know. ^^"
Oh right, tsukihime. It's on my laptop since two fuckin years and I always wanted to play it but I somehow ended up NOT playing it. I don't know what's wrong with me but I probably want to save something awesome for bad times.
Cross Channel's one of those games which you like, or not. Turned out that I don't like it. =\
Nope, there are always reasons why you like something but sometimes you just don't know about them. Anyway, this doesn't make it easier for us, so just pick one of the titles above and be fine...hopefully.
This and I personally won't buy me an Ipad, or something alike, anyway. I already have a shitty mobile phone (without cam etc.) and for everything else I can use my shitty laptop (which has a cam lol). Also, I can't enjoy playing visual novel while sitting in a train; I need my precious bed.
Well, ever17 and g-snm are pretty much unique so you won't find really similiar stuff. Anyway, it seems that you're basically searching for a visual novel with a good/deep story without a huge slice of life (empty talks) part. Let's see what I can recommend you...
Swan Song
Saya no Uta
Hanachirasu
Fate/stay night
Sharin no Kuni, Himawari no Shoujo
Sharin no Kuni, Yuukyuu no Shounenshoujo
Sekien no Inganock -What a Beautiful People-
Shikkoku no Sharnoth -What a Beautiful Tomorrow-
Just take a look at those visual novel and you'll probably find something interesting. If you've questions about a specific visual novel then ask.
