If you don't like arcade games or twitch-based shit, be prepared to be disappointed often. That's the main thing nobody ever mentions. Yes, it is still 50 games so statistically you may find something you like and in the end you may feel it was "worth" it overall, but so many games were "play for 5 minutes and then put down" for me.
I genuinely liked Rock On Island, Lords of Diskonia, and Party House. Even of those, Rock On Island is the only one I played significantly, probably about 10 hours and the only one I cherried. I think I'm largely done @ 45 hours, might come back for little nibbles here and there.
Mortol, Mooncat, Warptank, Pingolf, Quibble Race, Valbrace, Night Manor, Camouflage, and Vainger, Avianos are all "fine" I'd say (i.e. games I'd spend less than an hour on).
I think the fundamental issue with is I'd rather just buy 1 really good game that I love, instead of 49 that I like + 1 I love that is too short and simple.
But, I still feel I probably got my money's worth objectively, and that's the paradox. It's a volume approach.
