I used to belong to a squad in Warbirds, had a ton of fun flying with other guys...
there was no complex engine management (which was fine by me) and no external views, except bombers, I think....
the graphics are very dated and i don't see the appeal of offline with this, but if you could get into a decent squadron, it would be a lot of fun...
I still remember the first plane I ever shot down in Warbirds and have memories of many exciting missions, but I would not trade my IL2 for it...IL2 has such incredible content, great graphics AND online play for free...there is no comparison.
