Sid Meier's Starships
My first thought as soon as I opened the game was "wow this feels cheap." The feeling never went away, and just got even deeper. I was incredibly excited to see what the game would be like since it could be played on the go on an iPad, but if this is how they had to hamstring their design to fit a system like that, I'd rather keep the dream of on-the-go Firaxis games as just that: a dream, since the reality is just a disappointment.
Civilization V: Brave New World
Really, the best part about Brave New World is that it's finally addressed every victory condition in the game and made each one not only more equally viable, but also just as busy. Weaponizing culture works to bring it more in line with the other conditions--it's something you have to work towards and not something you just happen to achieve. On top of that, the diplomacy changes make this system more interesting as well, and it all comes down to one thing: if you have Civilization V and want to play more, you owe it to yourself to get this expansion.
Sid Meier's Civilization V
Civilization V is one of the best strategy games I have ever played. There are some issues but those are so minor in comparison to all the great things Firaxis has done to not only make this accessible to new players but even returning players as well. I can say with great confidence that you will not get a better game of strategy right now then what Civilization V has to offer, it is just that good.
