I finished SS First Encounter and played quite a bit of Second Encounter, and I still consider them two of the best pure shooters I've ever played. I only played the demo of SS 2, and I didn't think much of it. I did happen to purchase that today as well though since it was only another $3.40 to add.

I was thinking of doing a replay of Doom 3 next, but I'll probably play SS3 immediately afterwards.
