Simon the Sorcerer 1 is very good.
Simon the Sorcerer 2 is good.
Simon the Sorcerer 3 is bad.

Well your avatar would lead to a suggestion of broken sword 2 or 3.
Personal bias makes me suggest In Cold Blood

I already have the entire Broken Sword series.
I have wanted to try In Cold Blood... Maybe I should get that...

Duke Nukem 3D. If you've never played it before, you should. If you've played it before, the DukePlus and HRP mod will transform it into a very different kind of game
Actually everyone's recommending different games, and it'll probably add up to almost the entire GOG catalogue, so I think this thread isn't going to help you much
-edit-
Oh snap I just realised you've bought DN3D lol
In that case, I'd have to go with alias and suggest BS2 and 3

I already mentioned that I have the whole series :P
I'm thinking I'll get either Stronghold or In Cold Blood.

I highly recommend The Feeble Files. It's a hilarious adventure by the same company who make Simon Sorceror games.

I'm probably getting Febble Files this week. It's the only adventure game on GOG I've not played and looks realy nice.

I made my purchase. I bought In Cold Blood and Stronghold - and that's all the spending I'm doing until I get my new router ( the IRC guys will know my problems ).

If you are not using one already, do yourself a favor and buy a Linksys. I have used them for quite some time now and I haven't had any problems. If you did buy a Linksys router, then, maybe you got a built on a Friday, sold on a Monday model. XD

It was a Belkin G+ MIMO.
I just plugged it in again and it might be me imagining it but the GOG Downloader is now telling me I'm downloading ICB at 1600kb/s.
If it gives me any more trouble - I'm shutting it off completely.
My budget for a router will be around £50 and I'll be looking for a G+ or an N, if you know where I could get such a Linksys - let me know. And I don't suppose you know how Linksys adapters and things perform on Linux? Some routers have a lot of trouble - NETGEAR hardly works at all.
