ok so only 21 days so far.is it worth DLing it if its so short?im confused on the days.like week 1 is 16.6gigs but is 1 week.
Each day has a LOT of content. I'm working my way through Day 4. Actually, second time up to Day 4. I did four days of the vanilla game before installing the DM patch and Lain's mod. I'm now to the evening of Day 4, past where I'd been in vanilla. I'd definitely recommend Lain's mod so that you get to see more of the scenes. There are times when you're offered two or three options for an afternoon or an evening. Lain's mod allows you to see (and get credit for) all of the choices. Potential down side for some is that DM must be loaded, but one could configure it to take out most, if not all of the added content.
Others have played much longer than have I, so could tell you so much more.
