What I expected:... a more classy version of this mode. Like cliffs forming a path for the biters, limited building slots, upgrade-ability.
So, in factorio terms: Free turret construction, no need to craft bullets from materials, earning points to upgrade individual towers (like Ammo>piercing>radio ammo) or unlock new tech (flamethrowers), maybe some electric poles for laser turrets (for the factorio-touch and to stand out. After an hour, the game is either lost or maxed out and just a matter of time when it's lost.
My thoughts about current Tower Defense discussion
Things I "need" to give the current way of Tower Defense a serious try:
- biters attack objective only
- production cost
- map properties (if random generated - or select pre-built map)
- Short game times
- The way it is now
- ... -just- a common game with more aggressive biters and not 200k circuits/min in mind
- Classy version
- A lot more work and balancing issues - adding game-mechanics and way more effort
