It is super easy in this day and age to sell quickly, so it’s much less risky to buy without a test drive than it once was.
That being said, I personally never buy without playing because I really don’t enjoy the process of selling at all. Selling in order to make room for a new game has an obvious built-in reward in the end and is worth the hassle, but selling in order to mitigate disappointment resulting from a lack of due diligence before buying is really no fun at all!
