Similar topic was already touched here: Multicolored Gemstones that can be matched or paired together? . I remember that doomskulls were added to GoW not very long time ago, and I’m curious whether we have to expect other features from games with similar “Bejeweled” mechanics, “Puzzle Quest” first of them:
- Universal color gem, which matches any color (but not skulls nor doomskulls)
- Color bomb, which explodes when matched and maybe gives more mana (+5?)
They will surely change the current gameplay dramatically.
