Initially, certainly more impressed than anticipated/expected. Detail level is, again, ED standard, and especially immersive with the sound design and cockpit atmosphere. Definitely impressed with the flight model itself, and do not understand the discourse made about the lacking performance of it, as it seems equally matched in terms of dogfight capability; it just seems very fly-by-wire, as intended, compared to other F-1x equivalents - seemingly the source of some frustration about maneuverability in the simulator. Systems, sure, are indeed missing, but this was very expected in comparison to the F/A-18C release. Furthermore, there are some elementary features missing - damage modeling, external lighting, store management, etc. - but it seemed generally impressive overall as an EA module, like the F/A-18C. If anything, the F-16CM is just as capable in conventional combat scenarios than other airframes available, albeit without the unique/developed systems i.e. HTS, etc.
Overall, it's suitable for an EA module and it's eager for some systems work, but a decent start! Worth the preorder price.
