Just 2 weeks ago we started a test to see if we can earn some extra Steem to help the growth of 
Those who joined the game earlier did benefit from the surge in new players investing large sums of money. Now as the amount of players has grown and new upgrade money is being spread across a lot more players the prizes are decreasing. So without a massive surge of new players with a lot of steem to spend the prize pools will likely decrease over time as those with deep wallets that want to play the game likely have already invested their steem.
That said if you plan to play and haven't started make sure you understand that your results aren't going to be as good as ours even if all things were equal, but it's not equal if you were looking for an ROI. Drug Wars decided to reduce the amount of the money that would be paid out each day from new incoming funds. The total percentage of their earning going towards the prize pool stayed the same, but they reduced how much went to the next days payout. This drastically reduced the amount everyone is earning in the short term, but added to the games prize pool sustainability.
One last point. As all upgrades are priced in USD, but paid with steem the reward pool will shrink over time if we keep seeing the value of steem increase. This is outside of Drug Wars control and nothing they can do about the price fluctuations, but just wanted everyone to keep this in made after the day Steem just had. A few more large increases in Steem could drastically reduce the amount of new steem being added to the prize pool as it takes less steem per upgrade.
But if you want to play a game having some fun while earning some steem then this is a great option. This very well could still end up being a profitable game for those who play, but it will take you much longer then it did for

Final Thoughts
With the changes made to Drug Wars the payouts have decreased, but it should help with the long term sustainability of the game. It also moves the conversation away from making profits to game play which hopefully ends some of the ponzi scam talk that had been going around. Game play will start to reward those who play the game with skill once battles start which will make it more interesting for those who wanted to play the game....not farm steem rewards. Time will tell how this all plays out, but for now the game still allows for players to recover their investments (if you don't overdo it) in a reasonable amount of time and have a good time playing the game.
