You're welcome

Interesting, I've seen quite a lot of people from various gaming communities coming back to the old games 'recently'.
I guess that after 10~15 year's break people are looking back at the changes and try to refresh the memory of 'good old times' just for a moment.
I've seen it in various games - Quake/QuakeWorld, Q2, Q3/vq3 and cpma, and other. Of course technology goes forward an not everything is possible (like license servers are going offline), but they try to play the game at least for a moment.
I had that moment and played Q1 single player again like couple of years ago just for fun.

Now, refreshing all those memories linked to the HL series and other games....

The sad part - time moves on and not everything can be restored - just like a damaged picture found in the attic.

But still I hope I managed help you somehow.
