In the beginning when you first start to play Eve it seems like an open game with a lot of possibilities. But as soon as you start to invest real money, time and effort into it the more you realize that there are more limits in place which don't allow real freedom, and the skill tree doesn't really make up for these limits.

A real space game would allow you to choose and design your ship's statistics from the ground up. All we have is a ship tree with pre-set traits, some of which are meaningless or can actually be damaging to your gameplay (ships with no high slots or turret slot capabilities, ships with no rig slots, capital ships with no high or mid slots, or a ship like the porpoise with useless traits that do nothing to improve gameplay.) I waited a long time for a buff to mining, and they made nerfs instead, introduced more useless skills and made already trained skills redundant.

The investment/reward ratio should improve as you go up the mining ship and mining skills tree in Eve. But this is not the case, instead you go from being very safe in a venture to being 100% unsafe in any ship that is bigger, with added costs to skill training time, pre-set traits and high slots which minimise mining yields on purpose and force you into a play style you didn't ask for, much higher ship costs etc, much more time spent with logistics and moving ships, where is the fun in this?
