As far as I know for game inclusion criteria are as follows.
1.ww2 AC = no F86 for joo.
2.Squadron service lvls = no xplanes/testbeds/field mods.
3.Combat did shoot at something or was it shot at. self explanatory
The meteor fits this criteria.
Add one more.
4. It shot at an air target that could shoot back.
An Fi-103 (V-1 flying bomb) can't shoot back, so it doesn't count as an air target. The Meteor saw ONLY that and ground attack, and ONLY in the very last months of the war. Same reason we will never get the He-162 (also, the volksjager never did see widespread service, less even than the Meteor).
And do we REALLY need another uuber-ride? And one that's not even that good to begin with? The Mk.I was an abysmal jet, as far as jet's go. The Mk.III entered service within the last six moths of the war IIRC, and only saw service (and not much at that) as a ground attack jet.
