I just recently tried kingdom rush and liked it. However, it really bugs me that by the end of it, everyone basically has the exact same set of skills. My question is: are there any other TD gamed that have even more customization?
While Kingdom Rush indeed only has 4 towers to choose from, I would say it has one of the most deep and advance customization you can get. If you want tower choices, Fieldrunners 2 and Bloons TD 5 has lots of them.
Go with Defender Chronicles II for endless customization, upgrades, RPG elements, a ton of diversity, and never the same game twice. A very unique game in its own right.
DC2 is great, but it's quite different to the usual top down tower defence game. I can't really think of any other tower defence games that have lots of different upgrade choices though. GemCraft maybe?
You'd already mentioned both of those I was trying to think of any others The first sentence of the app description for E.R.A. put me off it, yes of course tower defence = place towers and wait (until I have enough money/energy/sun/whatever to place another tower), if I wanted to frantically tap at the screen I wouldn't be playing a tower defence game! It might be great though, I've not played it (well according to the App Store I've previously downloaded the lite version but I don't remember playing it).
Com2us has tower defense games but most if all are generic. Then there's sentinel series. I made a thread while back about tower defense games search and see if it is still there
Interesting, and I think you actually got a point I've just updated the description of the ERA TD and removed the first line, what we meant was we added something new such as tapping a creep to give attack priority and so on, but not so often or tiring at all, at the end of the day, we wanted to create something different
