A bit OT, but here's my take on Falcon 4 and Lock on
The 2 Sims fulfill the ideas of 2 different philosophies, A situational awareness/combat oriented sim, and a technical, avionics based sim. The former being lockon and the latter being Falcon. Neither is better than the other, it's simply a preference and is up to the individual do descide what he/she likes. ED, however, appears to be trying to combine these philosophies in DCS as an "ultimate" sim, which, IMO is a very good idea.
I got Falcon before Lockon, gave it a chance, and gave up, quickly finding lockon's more open/accessible game play more to my liking. I liked the idea of perfecting air to air combat tactics, rather than pressing every button in the cockpit. I also liked how lockon's training tutorials presented everything in a visual format, which allowed me (and other players I'm sure) to grasp the basics very quickly without flipping though a cumbersome electronic manual just to figure out how to access TWS. I prefer to be shown how to do something, not told how.
Both are good sims, it's just what the player prefers.
just my 2 cents
