I have to bow to you for actually separating the wheat (trash games, not really prestigious) from the chaff (real gems of the German community)

You have a top 10 list of "top rated" (left) and "most viewed". I don't know on what terms you choose games, but personally I would recommend "Die Reise ins All" ("Journey into space", quite a lot of german puns, fun to play), "Unterwegs in Düsterburg", or "Velsarbor" (virtually THE showcase RPGMaker game, quite impressive RPGMaker tech stuff) as LP's.
