MGO seems to be spending their massive warchest on exchange listings and hype material to pump the price. It's worked so far but who knows how long it will continue. There will be a token swap as well in which all Waves MGO tokens will be swapped for Ethereum MGO. This will increase the eMGO supply by 15%~. Many who are looking to buy in are waiting for this swap to take place as it could lead to a significant price decrease.
GAME is hit or miss. If you support the devs and the mission and believe in them it's a great price to buy at but there isn't much infrastructure to support it's current value. I personally hold some of each.
