I wasn't that impressed with Opposing Force, honestly. It was worth my time, but it doesn't go on my list of greats. I can say it was better than Blue Shift.
I think Episode 3 is pretty well under development.
In some interview, someone at Valve said that they basically view these episodes as the third installment in the series. Whether they'll make a proper Half-Life 3 is totally unknown.
I really hope they do, unless Episode 3 is 20 hours long and wraps up every loose end.
