I play in all the games you mentioned except cryptoshots which is on my list of games to try.
Soulkeep is a very fun game, I am doing well especially using the Epic Quad Killer towers.
The strategy I often use is:
In WAVE 1/x I immediately used the Spell CHEAPO which allowed me to reduce the mana cost of the first Quad Killer from 150 mana to 105 mana ;)
