As I've written before, I'm a huge fan of games that pack strategy into small packages. In fact, 'strategic choices per cubic inch' may in fact be my top criteria for a tabletop game (by this definition, for example, Bridge ranks right up there for me:).
Ultra Tiny Epic Galaxies outperforms in the denominator of that equation, as it is literally one of the smallest tabletop games available, fitting into a box whose form factor is essentially that of a standard pack of cards.
With respect to the the amount of strategy in the game - there's a bunch. In fact, it is clearly not the same game twice, as the rules changes enabled by the (dozens of available) different planets that are used each game make for important differences in how the experience goes. I thoroughly enjoyed the fast-moving challenges of deciding whether to expand my empire or exploit (ie orbit more thoroughly) various planets. The game is fun and plays quickly - I'd say budget thirty minutes per player. I particularly enjoy it with 3, although I am anxious actually to try it with 2.
More than once, players commented on how well UTEG was designed - the information is legible and well-plotted on all cards. I thought the rule book was well done and clear. As one who never travels without a tabletop game, I am particularly delighted by being able to bring a high-quality gaming experience with me wherever I go (I know, a pack of cards is a good substitute, but it simply can't compete with UTEG on THEME:) I also really appreciated not requiring a great deal of tabletop real estate when searching for a place to play - I'd say that less than one square foot per player is necessary for a full experience. I am anxious to get to UTEG to the table again. It pleases in many ways.
