Unlike some other sports games that have left made teams into the wayside (or replaced with fantasy-style Ultimate Teams at least), NBA 2K18 really features a very strong Create a Team. Not only can you make your own, you can play at a league filled with them.
The first thing you need to do is visit MyGM/MyLEAGUE from the primary menu of NBA 2K18. From there, go on over to MyLEAGUE and select to either perform a League Expansion or Custom League. Either one of these modes will give you an opportunity to plug in created teams in together with the real-life ones featured in the MT NBA 2K19 or even historical teams if you go the path of Custom League.
If you go for League Expansion, right off you'll be given an opportunity to produce around six new teams to add to the NBA's present 30. You can either create your own team from scratch, use a pre-built group or employ a group design from different users. Let us go with creating your own team as another two are fairly straightforward.
First, you will have to select your city, you have a number of unique locations throughout the country (and Canada) to pick from and you can factor in just how big the city is, how rich it is, and whether you are interested in being outside in the 'burbs or even the city's downtown area.
Following that, go on and create the group's branding. You can make your own logo, browse other users', select a preset, or even upload your own from the internet. In order to accomplish that, upload and follow the instructions there. Ensure that you satisfy all of the dimension requirements otherwise it will not allow you to proceed. If you upload a picture, give it a minute, then reopen the Team Branding section and it should look with another logos you've uploaded.
After that, you can begin designing your arena. Again everything from seat color, to what noise effects are used, what ads appear on the scorer's table and more can be customized to your liking to ensure your arena matches the personality of the group which you are creating.
Eventually go on and design the team's uniform. You can upload a logo to use and construct a uniform to suit, or simply keep it simple and basic with some regular ol' jerseys. It is up to you.
After that, you have inputted everything you require for your team to be created. Only following through on another teams you'll want to create, and once you're finished, you'll be playing an NBA season with very own established teams. Enjoy!
