(A different) BSGD here. I've taken a fair chunk of what this school has to offer (coding, design, some art classes, etc.) and this isn't my first college so I have an idea of what else is out there too.
As a DigiPen student coming in Fall 2016 (I presume?) expect a relatively (but not overly) crowded school. The students aren't all SJW, socially inept, etc., but they do exist and aren't rare. Not everyone is hygenic and not everyone gives a crap about any of their work (which is rather typical for college). I will say that this school has a lot more bureaucracy going on behind the scenes than any other school I've been to, which is a problem. This board makes it look worse than it is though since a lot of people come here to complain first and shitpost later. It's not Orwell's 1984 in here, don't worry.
As an RTIS student, you've chosen a good degree (if it turns out to be your thing). It's one of the better managed degree programs in the schools, and there's many good teachers for your classes. A lot of the complaining here comes from the GD programs, where the orgainization is poor, the teachers are hit-or-miss, and either the administration doesn't care or you have rather poor job prospects (though it's far from unfair or unusual for a college if you actually put effort into it).
Anyways, RTIS will still be a lot of work and if you can't manage your time you will be quickly swamped, but otherwise you'll just always be adequately busy and get used to it. It is more stressful than other schools in that regard, but you'll get a bit more out it than say Generica Community College's tech degree. Many state universities give DigiPen a run for their money in this regard though.
The main differences with DigiPen are that you get more thrown at you comparatively and the emphasis on projects. Getting in groups with people you probably don't know all that well in Freshman year is probably what generates most of the initial stress and ranting, but the group experience (and potential portfolio pieces for your resume) are of great value.
Also I don't eat here so I can't vouch for DigiPen's food (I hear it's hit or miss with a tendency towards misses) but Redmond has a number of places to eat at (besides the usual fast food) if you have money.
tl;dr Yes we have our weirdos and there's a lot of work, but if this school was a literal Hell it probably wouldn't be doing all that well financially. And it's doing quite well financially.
