Re: [DMM] Pero Pero Saimin
Yeah, ladder event is next. Not sure what planet of the sheep has to do with it though.

Lots of sheep themed games coming around because of the year.
It seems we've finally begun recycling cards now. Last event had the first limited card for inviting friends to join, and now this event will let you get the first event reward card. (Wedding dress girl.)
Muahahaha the last tab on the news section below the game is a questionnaire about the event, much like with the maze event, except multiple choice. I might try to translate it so we can all fill it out and complain about how horrible it was. xD The questionnaire ends Feb 4th, and anyone who fills it out will get a Peropurin for doing so. (I need like 600 after that event

)
Jan 28 from 3-9 AM local time DMM will be down, so either everything will be down, or you just won't be able to buy anything. Apparently the next event starts the 29th, so though it hasn't been announced yet, there should be a maintenance on that day, probably a 10AM-12PM deal.
As far as other games, there's quite a few though it depends what you enjoy. I'm currently rolling gachas for an upcoming game called SheepXChronicle. We'll see how that one turns out on the 2nd. It seems like Nutaku is trying to get the more popular DMM games Romanized so us westerners can join the fun. Lord of Walkure is already started though the events have yet to start, and it sounds like there are plans for PPS and Ageis.
