Adding a conditional is required to make a statement objective?
How about this;
"DA:I has poor keyboard and mouse controls". True or not, is this an objective or subjective statement? I have not said "in my opinion", or "everyone thinks". But I have made a statement which leaves no room for other opinions.
I can't see a situation where it would be necessary to proclaim "universal fact" if the "in my opinion" conditional has been omitted.
In this case I actually would say it's subjective, since assessments about "bad" or "good" are assumed subjective opinion.
Distinct from saying, for example, that something is "broken" which is a fact that can either be demonstrated or not.
Unplayable is something I count in the latter category, since whether someone is actually unable to play the game is something that isn't open to interpretation. Like "my car isn't starting."
When writing philosophy papers, you never say "in my opinion"* because it's assumed that statements which assert something are your opinion unless you assert a fact or the opinion of another, in which case you cite.
*This is also conditional on the culture, since in Japan for example you must write "I think" before anything you assert.
