I've played at games workshop with my son a few times in the past.
The rules were pretty simple and vague in the past. They've now made the rules even more simple for today's mentally deficient kids.
I do find Warhammer 40,000 pretty boring to play as it is too balanced and real warfare is about inbalance. Nobody attacks unless things are weighted in their favour, do they.
The normal Warhammer does allow for more tactics. I took a copule of units of cavalry around the edge of the table, turned in and attacked the Orc's big monster thingee (can't remember what it was but I managed to kill it!!) Anyhow, it must have been important to the Orcs as they started pulling units back from the front battle line to rescue it. This lost them the battle as our front battle line units out numbered them from that point. Yep, I did the classic cavalry sweep tactic. Many years of playing ACW, ECW, HYW, NW, etc. comes in handy.
As for Battle Fleet Gothic, it's the same as a galleon wargame except set in space and different weapons. Any galleon naval tactic will work in a game. It is extremely primitive compared to SFB and doesn't require a lot of brain power to play. The ships are extremly primitive and poor in armaments compared to SFB or FASA ships.
Basically, a Klingon D7K would have no problems taking out any BFG race's fleet single handed. Actually, make that an F5K!!
I use super glue gel by Flash (the yellow bottle) which sticks metal to resin to plastic. I've stuck bolt heads onto snapped off bolts on motorcycles with this stuff. Yep, its that good!!
The resin Soviet Tank models I use are by Red Star Models (UK) and includes everything from the MS1 to modern T80. I occasionally use two T35 Land Battleships in 1941 games. At wargames conventions they draw a lot of attention as any five turreted tank would do. They are pretty useless but do look impressive on the gaming table.
I use a routing bit to remove burrs and flashing on resin models.
