This is just a simple idea I had. Do not slay me if this idea has already been suggested in the past as I didn’t search before posting.
My idea for a game feature is one in which players could earn the ability through either VIP points, Purchasable add-Ons or through progression through several of the games different features to change the design of the gems that are used on the board. It could possibly present an avenue for revenue through in game purchases and would definitely cater more towards the hardcore GoW players and allow a player to really tweak the design and make it more their own. Adding a level of customization.
Then, you could take the idea even further and add game layout Templates as well, which could be obtained in one of the same fashions as I have listed above. Making the game even more customizable to each player and allow them to feel even more like their layout was more their own. Adding to the depth and provenance of their game experience.
These were just some ideas rolling around in my noggin’. I’m a relatively new player and haven’t progressed far in the game. But, I am one of those kind of players where if I invest monetarily in a F2P or P2W kind of game. I do truly enjoy customizable options. Not to mention, I am OCD as a mofo and love the ability to customize my game experience as much as a particular interface will let me.
