There's a few things I like about Enjin. First, they have a track record of successful execution, having built Enjin.com over the years into one of the most popular social gaming communities on the web. They have a total of 18 million registered users. A lot of ICO's are formed by people with good intentions, but even if they have a career history you can see on LinkedIn, you don't know if they can run their own business - that is a trial by fire and some people, even capable types who worked at top corporations, can't pull it off. The fact that the team at Enjin have been together a while, know the gaming market, and have built a successful business gives me more confidence that they can execute on their coin strategy.
Which brings me to the Second point, they intend to leverage their footprint with Enjin.com to make Enjin Coin available to the millions of gamers who already use their platform as a community for Minecraft/Guild/Clan websites. Essentially, teams of gamers already use Enjin.com regularly, and Enjin plans to offer them the opportunity to trade virtual goods player-to-player using Enjin Coin. This allows them to sell across games and for end-users to have true ownership of their virtual goods, being able to price and sell them in an open market. The fact that they have this "reach" into so many gamers could give the coin more traction. You can see some of those communities that have registered to use Enjin Coin here (https://www.enjin.com/communities). (Note: this is per Enjin's website and team- I have not verified this.)
The Third thing is that Enjin has an interesting strategy whereby they are incentivizing the groups that use Enjin to use Enjin Coin by giving them some number of free tokens (which they are setting aside during the ICO) based on how large and active the group is. This gives them additional incentive to encourage their community to use the token because it makes them invested in the outcome of the coin.
The gaming market is $108.9B in 2017; the market for social gaming (which includes ads in games, virtual goods, lead gen) is expected to be ~17.4B in 2019. It's a large, addressable market. To be fair, people should know Enjin is not the only game in town. There is GameCredits and MobileGo as existing digital coin solutions. But I believe Enjin has an advantage in accessing the market given its platform and reach, and a particular advantage with computer games (in contrast to mobile, console), where they have large loyal following.
I should disclose that I have invested in the Enjin Coin's ICO so take my opinion for what it's worth and do your own research.
