Like any recommendations list, there's a lot of stuff that is missing, but the list is more or less reliable. When you run out of VNs here, just go on [url=http://vndb.org/v/all?q=;fil=tagspoil-2 ... d;s=rating this list of translated VNs on vndb.org[/url] and look for any VN rated 7.5 or up or ask around here.(Like always OPINIONS apply). Anyways, there are some things I feel like pointing out.
Pacing Issues
Every VN longer than 10 hours.

Really bad pacing issues (Yeah, yeah, opinions)
Cross Channel
Clannad
Muv Luv Series
May have Willing Suspension of Disbelief issues (Again, OPINIONS)
Akabei Soft 2 (Sharin No Kuni, A Profile, G-Senjou No Maou)
Yume Miru Kusuri
Key Visual Arts (Clannad, Little Busters)
Post-Modernist as fuck (This is fact, not opinion.)
Forest
Happy reading.
