First off, Hello All. Long time lurker and only now decided to engage in the conversation.
Long ago, I was involved in the evaluation process for the original Lock-on. I unfortunately was so disappointed with it, mainly due to UBI not allowing ED to finish the product correctly, that the sim got shelved after just a couple of sessions.
Fortunatly, the Flight Sim bug bit me again this past summer and I decided to give FC2 a try. As a long time critic of ED (sorry, but true) I have to say I was really impressed. A lot of the issues we had with LOMAC seemed to have been addressed. My friends and I have enjoyed many an online session lately, with very little to complain about. Except not being able to put boats in the rivers in the ME! :) But that's just me.
