Obviously ambitious enough to create a masterpiece true to the original game, yet bold enough to explore flavorful new additions to gameplay that compliment the original. I hope to see that creativity continue exactly in this way, true to the original, and bold in continuing to add fine details to the players experience.
I would like to suggest one such fine detail, that would benefit the player and the player-base alike. Personal progress in enhancements of the players equipment, whereby the player may unlock a range of optics, silencers, and firearm accessories, as well as upgrades to tools, which stay with the player once unlocked.
Bottom line, progression of improving yourself by unlocking advanced playability with classes, equipment, upgrades, etc is a great way to enrich a players experience.
