They look like a sort of mealy bug to me. Spray isopropyl alcohol on them and if they turn red then definitely mealy bugs.
Get a cotton swab, spray it all down with alcohol and wipe them away and that should clear them up! Luckily they are pretty large and easy to see (at least more than other pests).
Mods can be an option but some are harder than others to use. I do find that a lot of mainstream games have a pretty good range of difficulties these days (including story mode etc), but definitely not all games.
