I can find no logical reason to not buy these game's I have not played but probably never will.
That's a lot of money. I always have a hard time with GOG because in general I feel they are way to expensive for 20 year old games.
Let me tell you a short story.
There is a guy on eBay called "AllVideo" who does nothing but sell older titles with a cheesy DosBox installer.
I bought a few games from him few years ago. To my amazement the games were replicated. So I complained to eBay. He refunded me.
I talked to a place that does replication from masters for educational titles and did Global Stars replications, actual creation of the CDROMS. I sent the CDROM off to them (Ultima Collection & X-Com). They told me I was right, they are in fact pirated.
Writeable CD's can be bought that look "silver" just like CD's that are out of the box per se and can be printed on. The printing they said appeared to be done with a high quality thermal printer.
I told eBay this. They asked for a statement from the replicator. So, they sent a statement. In fact, they sent it over and over. eBay refused to respond back to them. When I inquired again they said unless I am the VERO authorized person they will not act on it. I told them then just BUY one and send it out or have someone at eBay just heat or take a solvent and wipes off.
Wanted no part of it. Yet, best I can figure he makes between $3000-$5000 a month minimum and they do ZERO about it. I gave up which is exactly what eBay wanted me to do.
