Just noticed that Strong Bad is back but last time I tried the first episode it was borked and wouldn't start. As far as I could tell from some searching it's because older Telltale games don't play nice with modern processors.
If this is still the case than it's som propper BS of GOG to put it back on the store front.

Would you look at that, I reinstalled the first episode and now it works perfectly. The mad lads actually went and fixed it from crashing at launch.
