Slightly shocked that I have 148 games in GOG. I thought I had maybe about 20 or so. Those casual purchases sure mount up. I had a steam account but never bought anything, always-online pisses me off but GOG seems to have gone that way and so's everything else so now I guess I don't use steam because it has no relevance to me rather for any misunderstanding about how it works on my part.
Probably 10-20 of my GOG stuff would have been the freebies, certainly some (lots) in there I have no recollection of and will probably never play. Others I bought in series that ONE DAY I will try to play, others where I wanted one game but there were four related ones so I bought them too. And then there's those long-winded RPGs I bought because I liked Blizzard games and wanted to branch out a bit; or I thought Syberia looked like it might be a kind of point and click Tomb Raider (that a post-purchase rationalisation). Add in a few that were things I had on disk but can't be bothered to set up myself on Windows 10 so I bought them too...
Jeez. I think I may have tried (as GOG installs) about 20 of these, a lot of which made me completely depressed within minutes (or seconds) of starting (I suppose because they were crap, or turned out to be aimed at children, or because I played WoW too much and playing on my own for more than 5 minutes, even if wouldn't have talked to anyone for hours in WoW - I hate guilds - makes me feel isolated and lonely), others I tried for longer but have now forgotten what I was doing so that ain't gonna happen soon (dungeon-sorta things like Grimrock or Planescape - which I loved but put down sooo long ago), and others (those damn RPGs I keep buying) I just start them and think "goddamit this looks like a lot of work... maybe not now... or ever....". Y'know, where you have forty options to set and have to choose your hair and how close together your eyes are, as well as a pile of stats that don't mean anything to you but you wanna do it right first time because it looks like once through will take a lifetime...
I would like to replay Lichdom Mage because I remember that literally made me giggle.
