Some of the GDW titles were what we would today call easy play and others were meatier, so too much of a mixed bag for a broad compare, but i would say that this is more accessible than anything put out by GDW, other than the mentioned Battle for Moscow.
GDW did put out several 8 and 12 page rules designs, which though heavier than VK, not excessively so.
GDW did produce the 120 series (120 counters playable in 120 minutes) and I understand that Compass Games are planning to release three of these titles in the future.
