yea, I don't think Opus Magnum is my favorite either. I just think it's a good starter, to get a gentler introduction to the many-step puzzles and those optimized-build leaderboards - if those leaderboards call to you and you like fighting your way towards the left, you're going to be a Zachtronics addict in no time.
if you don't enjoy them, then you've at least had a sizable taste of the mechanics and know why it's not your thing, rather than getting hard-blocked early on because you couldn't figure out a trick :)
