As above it's both possible to play on an underspecced system (generally low settings and/or reduced resolution) and also obtain a Steam refund if it's been within a week or two and you have less than 2 hours of game time.
My son plays Rec Room on 3470s integrated graphics (minimum spec listed 290/970), it's definitely choppy but still playable, as an example.
It also depends specifically which 200 series card you have, but it should be close enough anyway to be playable since the minimum was a 270x.
