Topic: Name some english Galge

Im an otaku for years now, i collect manga and anime, figurines and dakimakuras and other stuff too i also play many games but i never really got to play a galge. Recently after watching several anime like Outbreak Company and Gate where they mention them a lot ot the time, ive started to want to try some. As i dont really know where to start i thought i as around and see what ppl would recommend. It can be 18+ or not, doujin or commercial, as long as it in english. Could anyone name some games you would recommend,
