I'm okay with the internet thing. You only need to be connected to the internet when the game downloads content? I can't remember. I can see how it'd be annoying, but I tend to play on wifi at home so it never affects me too badly.
I like some Voltage games, but sometimes they can be hit and miss. Some Voltage games are great, but a few don't have a lot of content, quality writing, etc.. I tend to wait for other people to recommend Voltage games to me before buying them. Also, sometimes Voltage bishies look too much alike and have similar personalities across games. Every so often I run into a gem, though, and Voltage does seem to be trying to expand their art style with some games. I appreciate their games with Western-style art and settings.
I remember thinking "Pirates in Love" was the BEST. It was my first Voltage game, and I wanted a mobile otome game so much... Now you can't throw a rock in the app store without hitting an otome game. LOVE IT.
I played Niflheim, which has beautiful art, compelling characters, and a wonderful world. BUT, the freemium game structure really impairs my enjoyment. The individual scenes seem short, and there isn't a whole lot of romance until you worked up to the very end (which takes DAYS AND DAYS). Still, Skeletano~ The ROs are all interesting, which is what got me to slog through the awful freemium bs. I can't stand that whole "hey, dress up your avatar in arbitrary outfits that don't really affect the game at all except when the game needs an obstacle for you to unlock (yay...)"
Meanwhile, I started playing (throwing money at) Mystic Messenger. Although I should know better, I'm really obsessed now. 707 is cute, unique, fun, quirky, and my dream guy. Usually I don't like the Freemium play structure, but the writing and content is good enough where I actually don't mind that much. I've had NO patience for waiting for chats to open up, and so I've spent a lot of money on this goddamn game.... Just... so... in... love... with... 707. His cardboard prank for he April Fools special had me rolling on the floor. It's definitely worth getting. His Valentines Day special is worth getting, too. Unlike the other guys, the MC makes choices that determines which ending you get (romantic and innocent, or sexy and sexy).
I really like Cheritz (I played Dandelion). Generally, I get caught up in their stories and characters. With some other games, I end up skipping a lot because I get so bored. But MM has sucked me in.
The only thing that turned me off to Dandelion initially was how slow the start felt. It seemed to take forever to get to any otome content. I played it a long time ago, though, so maybe it's not the slog I remember it to be. I haven't played Nameless, but I need to.
Lastly, Resident Evil 4: Otome Ediion
Haven't played this. I think it's a Nano, but, man, it looks stupidly funny.
