I just don't know. i have played every one but have been less excited with everyone. The one i played the most was 2, even with the cheating AI, 3 i played less and so on. I have the complete IV and V and havent played them much, V just didnt grab me, like JD said felt like a lot of hit end turn. I've watched some vids of VI and it looks good, i like the looks of the changes. i will probably pick it up at some point but way later in a complete bundle, i might just be tired of the formula. For my 4X fix i prefer endless legend these days, i like the tactical battles. I still haven't played it much or Age of wonders 3 which i also own.
