If you have the time to invest, go ahead. The problem that eventually ensues in Tarkov is not being able to keep up with the competition. In the beginning, everybody is in a similar state, little to nothing in terms of equipment (Aside from those with the good Tarkov Package) - Eventually, people are able to equip themselves with more 'durable' equipment and soon you'll be outgunned.
