A few days ago, I decided to finaly try TI myself, as I heard how cool is it. Indeed, it was. I have the feeling no original mods will be made after this, as you pushed TS to it's limits. However, there are problems...
Pro:
-The new structures have epic looks
-Great visual and even greater sound effects
-Original ideas, like the spider web fence
-Good looking terrarin and vehicles
-Good music
-More realistic damage system
-Wonderful AI
Contra
-Oversized vehicles clipping into each other in groups
-Downsized infantry look horrible
-The f*ing loud alarm sound sensors make is annoying as hell
-Eclipse tank is OP, while goliath is useless
-On Lambda City (2), Nod has huge advantage: they can get cheap harvesters by hijacking the globotech harvesters early game, and mole artillery has a great range, so you can bombard the enemy from the doorstep of your own base. Also, if you build your base like 10 cells closer to theirs, you can destroy them with moles from your own base.
-Radar scan drone is buggy, sometimes it does not reveal anything, also, it damages units.
-Cliff errors on some maps
-Useless earthquake generator thing
-AI tends to waste ion cannon shots
-No random map generator
Despite the problems (I know you will fix most of them), even in beta, TI is the best TS mod to date.
