Um, I am not against large tech trees, I am against a lot of meaningless inventions and discoveries. MoO featured different tech at every level and each new ship hull, for example, was a huge step forward. But when you have Laser I then Laser II 3 turns later, then Laser III 3 turns later and each tech hold ONLY new laser version then they become worthless. For example, MoO tech tree: <img src="http://1.bp.blogspot.com/-2p5S13u-G24/TiIymfjXiAI/AAAAAAAAACE/LUGjfZ_JG-w/s1600/Moo

Almost all Civilization and some global strategy games had one flaw - sometimes new units\chassis\ship hulls become obsolete way too fast. So players do not bother with building some units and just wait till they get more powerful versions of desired technology. Like ignoring battleships when Dreadnoughts are several turns away. Same goes for weapons - ignoring, for example, Laser II then you could get Laser III after a couple of turns and Laser IV is much much further down the tech t

Free space have been such a precious resource that it was million times easier to build more invasion ships than to lose even one tile. Then, if you have to take small planet of 6 or so tiles, then losing one to three tiles will effectively render it worthless. So, the only viable invasion tactics I saw was the ones that left PQ intact.Entire swath of invasion option
Sadly, we saw that in Endless Space already. Tactic cards, different speed and accuracy of different weapon types - in the end players reverted to refitting. Just because refitting is much more benefical than all tactics and other bonuses.
GalCiv suffered immensely from Rock-Paper-Scissors approach to armor and weapons. Just like Endless Space it featured 3 weapon types and 3 armor types. In the end it all boiledto how fast players could refit their ships to match the enemy. Enemy has missiles and deflectors? Refit to Rockets and ECM. Beams with Armor? Refit to Deflectors with Rockets. And so on. It does not require any strategy, tactical sence or anything else - you just look at what enemy has and change ship l
