Well, one thing is certain. We can't count on RSE/UBI to come up with anything close to what it appears is being done here. I am sure Wildlands will fall short as did the Division . If there were possible more help to make a few updated maps with interesting additions, we all may be surprised, otherwise it will be overwhelmingly difficult for one or two people to achieve a project like this. Then people will surely, not be satisfied because they will say there aren't but "X" number of maps. This appears to be for the GR community, not just for a handful of people.
Lightspeed, you made great modded maps, I am sure you can understand the effort being put forth to get this on a new engine. Gameplay will not change from what I see from OGR. It may require much more skill than OGR. Something we do not find in today's run n gun games.
So, I guess we will see. One thing is for certain, it's a great start. Maybe we will see what the response is from Marz1.
