That's all opinion though - I thought the XCOM reboot was very, very well done - depth in gameplay without getting unwieldy with detail. It's a very different game to HoI, of course, but I think it's success was due to it doubling-down on quality rather than quantity. From the many I know who played it, I doubt they would have enjoyed it as much if it was 'just' the original X-COM with a shiny coat of 2000's visuals.
The new XCOM was great, although it was a shame it was fairly buggy and not patched very quickly/much. However, if you haven't tried the Long war mod you should really check it out - it takes new XCOM and turns the dial up to 11.
