I bought Black Shark. It was fun for a month then it was the same ol, same ol. But it's a chopper that has a total production of 10. That's not a typo. I haven't flown it in years, so it's a no brainer that I didn't buy BS2. P51? Wrong time frame and nothing to fly against but modern ground vehicles or other P51's. Didn't buy it. Combat Arms? It's a beta, been down this road before and the terrain needs several things before CA becomes something I'd be interested in. Collision models for trees for example. Now a Huey? To fly what, resupply missions? It's a light skinned, slow moving target that cannot survive on the battlefield w/out support. Like other choppers. The weapons it carries aren't even capable of killing a tank. Even an old T-55. So no purchase for me.
I'm not wanting to be critical here but I'm just giving my personal opinion on why I didn't purchase these modules. My squadron feels roughly the same way so I doubt that there will be any sales of the same modules with them. This is in stark contrast to my previous purchases, which is everything from LOMAC to DCS: Warthog I and my squadron bought every copy of.
I wish TFC and ED well with their future endeavors and I hope they sell enough copies of DCS: Huey to make it a profitable module. Unfortunately it's not what the majority of us want. Modern fast movers in high fidelity is what the community is craving. Doesn't matter if they're strictly air superiority like the F-15 or something multirole like an F-16 or F-18. But that's what the community wants. Fast ground attack jets are wanted. I'll bet DCS: Warthog sold a butt-load of copies. Judging by the participation on the forums, the Frogfoot and the Hawg are the two most popular "modules" out, and surpassing that is the excitement that FC3 will be released and incorporated into world. I predict that the medium fidelity FC3 will be the best selling module ED has released and will only be surpassed in sales by a fast mover module.
There is a niche for products like the P-51 and the Huey, but with no new theatres of operation as well as period correct enemy a/c and ground units these modules are just a passing "fad". I doubt they'll have legs.
